+Version 0.57 to 0.58 (3-JUN-1999)
+====================
+
+Bug fixes
+---------
+
+ - ENI drivers sometimes directly dereferenced pointers instead of using readl/
+ writel (fixed by Mitchell Blank)
+ - nicstar driver no longer uses floating point (fixed by Rui Prior)
+ - nicstar driver may have refused CBR VC in some cases even with enough
+ bandwidth available (fixed by Rui Prior)
+ - usage.tex failed to build (fixed by Bill Brooks)
+ - zeppelin got byte order in BLLI wrong (reported by Chas Williams; fixed by
+ Mitchell Blank and Heikki Vatiainen)
+ - zeppelin did not work when the host had multiple ATM addresses (reported by
+ Benoit Steiner; fixed by Heikki Vatiainen)
+ - zeppelin incorrectly parsed -i command line option (reported by Benoit
+ Steiner; fixed by Heikki Vatiainen)
+ - atm_connect_vcc and /proc/atm/pvc report AAL0 now properly (reported by Zhu
+ Qun Ying and Uwe Dannowski)
+
+New features
+------------
+
+ - nicstar driver now support SONET diagnostics (by Rui Prior)
+ - nicstar driver now works on PowerPC (by Jay Talbott)
+ - LANE now also supports Token Ring (Heikki Vatiainen, with testing by
+ Holger Smolinski)
+
+Other changes
+-------------
+
+ - major non-i386 architecture and other cleanup in ENI driver (by Mitchell
+ Blank)
+ - number of lec devices is 40+8 (lec0-lec39 are Ethernet and lec40-lec47 are
+ Token Ring; Heikki Vatiainen)
+ - lec.c and mpc.c now use atm_force_charge (Heikki Vatiainen)
+ - net/802/tr.c limited interface names to 4 characters (fixed by Heikki
+ Vatiainen)
+ - zeppelin man page updated (Heikki Vatiainen)
+ - "zeppelin.new" is now "zeppelin", the old "zeppelin" is gone
+ - set "atm_connect" printk to KERN_DEBUG
+ - removed ATM_SAAL from include/linux/atm.h (there never was any support for
+ SAAL in the kernel)
+
+

-* Module Name:
-* addr_reg.h
-*
-* Abstract:
-* This file is the interface to the ATM address registration.
-*
-* Authors:
-* DMW - Douglas M. Washabaugh
-* TLR - Theodore L. Ross
-*
-* Modification History:
-* Date Name Description
-* 06-Oct-94 DMW Created.
-* 07-Nov-94 DMW Updated with review comments, reversed order of routines.
-* 29-Mar-95 TLR Changed callback typedef to a pointer.
-* 16-May-95 TLR Added support for event reporting.
-* 06-Sep-95 TLR Added special address allocation call.
-*
-* Description:
-*
-* MANAGEMENT INTEFACE:
-*
-* The management interface does not perform any work, but enables applications
-* to have some visibility into this module. Currently the management
-* interface exports functions to determine the state of address registration
-* and to get a list of the ATM addresses that have been registered. Generally
-* these routines can be called at any time.
-*
-* Call Sequence:
-* addr_reg_create - Creates an instance, inits the MAC addresses.
-* addr_reg_client_register - Client registers
-* addr_reg_atm_addr_alloc - Gets and registers an ATM address.
-* addr_reg_atm_addr_dealloc - Deregister an ATM address.
-* addr_reg_destroy - Returns any allocated resources.
-*
-* Issues:
-* - Do the clients need to be able to deregister themselves? Currently this
-* interface assumes that they do not.
-*
-* - Does the management interface require the state of each client? Does
-* it require a list of clients?

-* ---------------------
-*
-* Overview:
-* This is the callback made whenever an address is invalidated or registered.
-* In the event an address is invalidated, the selector of the address is not
-* significant. All addresses with the provided prefix and ESI are to be
-* considered invalidated by this single callback.
-*
-* Arguments:
-* context - (IN) The caller context (handle) that was specified when
-* the address was registered.
-*
-* p_atm_addr - (IN) Pointer to the ATM address that was registered. This
-* pointer is only valid in the callback routine. It
-* may not be saved away. Instead, the ATM address must
-* be copied.
-*
-* event - (IN) The event associated with the ATM address. The event
-* is one of: ADDR_REG_ADDR_EVENT_REGISTERED,
-* ADDR_REG_ADDR_EVENT_INVALIDATED.

-*
-* Overview:
-* Registers a client. After a client is registered, it may register and
-* deregister ATM addresses. A client must
-* register so that it can be told about changes in ATM addresses.
-*
-* Arguments:
-* addr_reg_handle - (IN) The handle that was returned from addr_reg_create.
-*
-* p_callback - (IN) A pointer to a routine to call when an ATM address
-* registration or deregistration has completed.
-*

-* STATUS_K_PENDING - Operation successfully queued.
-* STATUS_K_BUSY - Client already has a pending operation.
-*
-* Preconditions:

-* - The routine addr_reg_client_register was called.
-*
-* Postconditions:
-* The registration of the address will start at the next opportunity. An

-* 19-Jan-95 TLR Added length parameters to the transmit and receive calls.
-* 15-Feb-95 TLR Updated SVC Information Block Types. Added AAL Data.
-*
-* Dependencies:
-* types.h - Generally used type definitions.
-* codes.h - Completion codes.
-* lane_atm.h - ATM specific definitions and types.
-* svc_info.h - SVC Information Block Definitions.
-*
-* Description:
-*
-* The Connection Manager (CM) exports this interface to software entities
-* called Service Access Points (SAPs) which communicate over an ATM
-* network. The SAP is a registration interface to which at any time an
-* arbitrary number of SAP entities may register.
-*
-* A SAP may open and communicate on any number of VCs. A SAP may also use a
-* mix of Permanent Virtual Channels (PVCs) and Switched Virtual Channels
-* (SVCs).
-*
-* The SAP interface provides the following basic services:
-*
-* - Setup and Teardown of PVCs,
-* - Setup and Teardown of SVCs,
-* - Packet Transmission based on Connection or ATM Address,
-* - Demultiplexing of Received Packets to SAPs.
-*
-* This module assumes that any synchronization issues are handled externally.
-* It is assumed that there is at most one process thread running in each
-* instance of the module at any time.
-*
-* The CM handles transmit and receive packets. It is not concerned with the
-* format of the packets and does not look into the contents of packets. The
-* CM simply treats each packet as a pointer to void. The CM's neighboring
-* components must agree on the format of data packets
-*
-* Concepts:
-*
-* Connection Handle:
-*
-* Connection handles are used to uniquely identify individual PVCs and
-* SVCs. Connection handles are more abstract than VCIs because the VCI
-* is not always known during the life of an SVC. At circuit setup time,
-* the Connection Manager provides a connection handle that the SAP must
-* subsequently use.
-*
-* Connection Context:
-*
-* Connection contexts are defined by SAP clients and are opaque to the
-* Connection Manager. These contexts are provided by the SAP client during
-* VC setup and are stored by the Connection Manager with the other VC
-* information. The connection context is passed back to the SAP in each
-* callback that is specific to a particular VC. For example, each packet
-* received is passed to the SAP along with the connection context for the
-* VC on which that packet was received.
-*
-* User Data:
-*
-*
-* AAL Data:
-*
-* The connection manager is not specific to any particular ATM Adaptation
-* Layer (AAL). An AAL_Data field is passed along with each transmit and
-* receive packet. Refer to the definition of AAL_DATA in the "lane_atm.h"
-* header file.

- * multipoint SVC.
- *
- * CONN_PARTY_DROP....An endpoint was dropped from a point-to-multipoint

- * a requested add party operation failed.
- *
- * CONN_STALL.........This event occurs when a VC is stalled for any reason.
- * VCs become stalled as a result of flow-control credit
- * resynchronization or by network management action.
- * The stalled event will not occur as a result of

- *
- * LEC_NETWORK_AVAILABLE......The LEC has just successfully completed the
- * join process and is ready to provide
- * communication services with the newly
- * connected Emulated LAN.
- *
- * LEC_NETWORK_UNAVAILABLE....The LEC has just detected a network error
- * that is severe enough to cause membership in
- * the ELAN to be dropped. This is either due to
- * loss of a critical control connection or loss
- * of the ATM link to the adjacent switch. In
- * either case, the LEC has begun to attempt to
- * rejoin the ELAN with the parameters supplied by
- * the registered user during registration.

-*
-* Overview:
-* Callback that is called when a packet is received on the emulated LAN.
-* A pointer to this routine is supplied at registration time by the user.
-* Note that this callback will not be invoked for packets that were received
-* but filtered by one of the receive packet filters.
-*
-* Arguments:
-* context - (IN) Context value supplied at registration time.
-* length - (IN) Length of the packet in bytes.
-* pp_pkt - (IO) Pointer to a pointer to the received packet structure.
-* The returned value of this pointer refers to a buffer
-* that may be freed by the lower driver. If the received
-* packet was copied, the pointer may be returned
-* unchanged. If a fresh buffer is to replace the
-* received one, a pointer to the fresh buffer must be
-* returned. If there are no free buffers, a NULL pointer

-* Date Name Description
-* 2-Feb-95 TLR Created.
-*
-* Description:
-* The LE-ARP cache module maintains the relationships between MAC addresses
-* and VCCs. It shares the ATM address list and VC list owned by the
-* Connection Manager. This module performs the following tasks:
-*
-* 1. Resolves MAC addresses to VCCs for every transmitted data frame.
-*
-* 2. Performs the two-tiered ARP refresh algorithm specified in the
-* ATM Forum Specification.
-*
-* 3. Keeps track of data frames flooded and limits the rate based on
-* ATM Forum parameters C10 and C11.
-*
-* 4. Drives the Flush protocol when data path switching takes place.
-*
-* Note that this module does not deal with frame formats or data transmission
-* or reception. It uses the services of the LEC_CTRL module for these.
-*
-* Call Sequence Requirements:
-*
-* The following diagram depicts the call sequence constraints: Functions
-* with lesser indentation must be called before function with greater
-* indentation.
-*
-* - la_create
-* - la_register
-* - la_config
-* - la_arp_resolve
-* - la_addr_delete
-* - la_arp_update
-* - la_flush_complete
-* - la_topology_change_set
-* - la_vc_added
-* - la_vc_deleted
-* - la_deregister
-* - la_destroy
-*
-* Example Usage Scenario:
-*
-* la_create...............This call is made as a result of the creation of
-* the LAN Emulation Client super-component.
-* la_create is called by lc_create.
-*
-* la_register.............When a protocol registers with the LEC and requests
-* that an ELAN be joined, this call results. A new
-* LE-ARP cache instance is allocated and initialized
-* to contain no entries.
-*
-* la_config...............This call is used to configure the LE-ARP cache
-* with parameters needed to operate. This call is
-* made once the configuration phase of the join is
-* complete and the parameters are known.
-*
-* la_arp_resolve..........This is called each time a transmit data packet is
-* sent by the protocol. In this case, the
-* destination MAC address is not in the LE-ARP cache
-* so a new entry is created and the cache begins to
-* attempt to resolve the address to a VC.
-*
-* (arp_xmt_callback)......Still in the context of the above call, the cache
-* uses this callback to request the transmission of
-* an LE-ARP request frame.
-*
-* la_arp_resolve..........This call is for the second data packet to the same
-* MAC address destination. This time, the cache
-* finds an entry with the MAC address but since the
-* resolution to a VC is not complete, the packet must
-* be either flooded or discarded depending on how
-* many packets have been flooded recently.
-*
-* la_arp_update...........The network has responded to the LE-ARP request
-* with an LE-ARP response. The cache now knows the
-* mapping from the MAC address to the ATM address.
-*
-* (svc_setup_callback)....Still in the context of the above call, the cache
-* finds that there is no SVC associated with the
-* ATM address in the new mapping so it uses this
-* callback to request that a VC be set up.
-*
-* la_vc_added.............When the new SVC is finally set up, the LEC_CTRL
-* module uses this call to notify the LE-ARP cache.
-* The MAC address entry is now associated with a
-* data-direct VCC.
-*
-* (flush_xmt_callback)....Still in the context of the above call, the cache
-* uses this callback to request the transmission of
-* a flush request on the broadcast channel.
-*
-* la_arp_resolve..........The next packet to the same MAC address is being
-* resolved. Since the fluch protocol is in process,
-* this packet must be discarded. The return value
-* of this call indicates MUST_DISCARD.
-*
-* la_flush_complete.......The flush protocol is complete because a flush
-* response has been received for the MAC address.
-* The cache updates the entry to allow data-direct
-* transmission.
-*
-* la_arp_resolve..........The next packet is finally resolved to an open
-* data-direct VCC.
-*
-* la_deregister...........This call is made when the ELAN is unjoined by the
-* protocol.
-*
-* la_destroy..............This call destroys the instance of the LE-ARP
-* cache.

-* Module Name:
-* lec_ctrl.h
-*
-* Overview:
-* The LEC_CTRL module is a subcomponent of the LAN Emulation client (LEC)
-* module. It is responsible for all of the control aspects of LAN Emulation
-* clienthood. It implements the LEC state machine and handles all LE control
-* packets.
-*
-* Authors:
-* TLR - Theodore L. Ross
-*
-* Modification History:
-* Date Name Description
-* 4-Oct-94 TLR Created.
-*
-* Description:
-*
-* Data SAP Requirements:
-* The LEC_DATA module is the user of this interface to the LEC_CTRL module.
-* Each instance of the LEC_DATA module joins an ELAN. In the process, it
-* must first register with the LEC_CTRL module (via lc_register) to obtain
-* an lc_elan_handle. This handle uniquely represents this ELAN's LEC_CTRL
-* instance.
-*
-* Once LEC_CTRL registration is successful, the LEC_DATA instance must
-* register with the Connection Manager (CM) as a SAP client. In so doing,
-* it MUST provide the following arguments:
-*
-* - The 'sap_context' MUST be the lc_elan_handle returned by lc_register.
-*
-* - The 'vc_notify_callback' MUST be the lc_sap_vc_notify function
-* described in this interface.
-*
-* - The 'svc_connect_callback' MUST be the lc_sap_connect function
-* described in this interface.
-*
-* - The 'link_status_callback' MAY be ignored by specifying it as NULL.
-*
-* Call Sequence Requirements:
-*
-* - lc_create
-* - lc_register
-* - lc_join_start
-* - (ELAN_STATUS_CALLBACK)
-* - lc_addr_resolve
-* - lc_deregister
-* - lc_destroy
-*
-* Example Usage Scenario (callbacks are shown in parentheses):
-*
-* lc_create...............At system initialization time, an instance of the
-* LEC module is created.
-* lc_register.............
-* lc_join_start...........
-* (elan_status_callback)..
-* lc_addr_resolve.........

-* changed. Either the ELAN has become available or it has become
-* unavailable.
-*
-* ELAN availability differs from Link Status in that an ELAN is not available
-* until the link becomes available AND the join process is completed.
-*
-* Arguments:
-* ld_elan_handle - (IN) Handle describing the ELAN instance of the data
-* module.
-*
-* elan_available - (IN) Boolean value indicating whether the ELAN has become
-* available or unavailable.
-*
-* mac_addr - (IN) The MAC address for this station in this ELAN.
-*
-* lan_mtu - (IN) MTU size of the ELAN.
-*
-* p_elan_name - (IN) Name of the ELAN.
-*
-* lec_id - (IN) LEC_ID of this LEC in the newly joined ELAN.

-* Module Name:
-* system.h
-*
-* Abstract:
-* This module defines system specific items. The definitions in this file
-* are available to all of the system modules.
-*
-* Authors:
-* TLR - Theodore L. Ross
-*
-* Modification History:
-* Date Name Description
-* 27-Oct-94 TLR Created.
-* 03-Feb-95 PJR Updated bit masks to allow for 32 bit user_data.
-* Added USER_DATA_LEH_MASK to extract the header.
-* Removed len field from INT_BUF, length is passed
-* separately to the lower driver.
-* Added USER_DATA_ADD_HDR_MASK to test the add
-* lan emulation header bit.
-* 06-Mar-95 JAD Removed INT_BUF.
-*
-* Description:
-*
---*/
-
-/* USER_DATA
- *
- * This value is passed between upper layer SAPs and the lower device
- * driver through the Connection Manager (CM) with every packet. For transmit
- * packets, it contains information about the buffer format and how the buffer
- * should be deallocated by the driver.
- *
- * +---+---+---+----------------+-------------------------------------+
- * | 1 | 1 | 1 | 13 | 16 |
- * +---+---+---+----------------+-------------------------------------+
- * | | | | |
- * | | | | +-- header_data
- * | | | +------------------- reserved
- * | | +----------------------------- add_snap_header
- * | +--------------------------------- add_le_header
- * +------------------------------------- internal_source
- *
- * USER_DATA contains the following fields:
- *
- * internal_source...If this bit is set, the transmit packet associated
- * with this user_data was generated internally. This
- * means that the packet was generated by a component of
- * the ATM system (i.e. Signaling, UME, Lan Emulation,
- * etc.). The driver must treat this buffer as an
- * internal buffer and not as an operating system
- * generated packet.
- *
- * add_le_header.....If this bit is set, the transmit packet associated
- * with this user_data is a LAN Emulation packet. The
- * driver must add the supplied LAN Emulation header to
- * the packet as an added fragment.
- *
- * add_snap_header...If this bit is set, the transmit packet associated
- * with this user_data is a Classical-IP (RFC 1577)
- * packet. The driver must prepend a SNAP header with
- * the supplied Protocol ID (PID).
- *
- * reserved..........Reserved for future extension.
- *
- * header_data.......Either the two octet LAN Emulation header or the PID
- * of the SNAP header to be prepended to the packet if
- * the 'add_le_header' or 'add_snap_header' bits are set
- * respectively.
- *
- * Invariant:
- *
- * At most one of the following bits may be set in the user_data:
- *
- * internal_source
- * add_le_header
- * add_snap_header
- *
- * The lower driver must never be required to prepend a header on an
- * internally generated packet.

- *
- * This type enumerates the possible link state events that can be

- *
- * LINK_EVENT_PHY_DOWN........Carrier was lost on the physical port.
- * The link state will transition to
- * LINK_DOWN after a hysteresis period
- * elapses (around 3 seconds).
- *
- * LINK_EVENT_PHY_UP..........Carrier is up on the physical port.
- * Link state transitions immediately from

- * peer is complete. Link state transitions
- * immediately from LINK_PHY_UP to LINK_LINE_UP.
- *
- * LINK_EVENT_SIG_UP..........The Signaling transport (i.e. QSAAL) has
- * completed its connection with its peer.
- * The link state transitions immediately from
- * LINK_LINE_UP to LINK_SIG_UP.
- *
- * LINK_EVENT_SIG_DOWN........The Signaling transport has lost contact
- * with its peer. The link state transitions
- * immediately from LINK_SIG_UP to LINK_LINE_UP.
- * All SVCs are deleted in an orderly way (i.e.
- * the driver is asked to teardown the VCs).
- *
- * LINK_EVENT_RESET_START.....The driver is resetting. The link state
- * transitions immediately from wherever it is
- * to LINK_DOWN. All SVCs are deleted harshly
- * (i.e. the records are simply deleted, no
- * notification goes to either the signaling
- * function or the device driver).

- * LINK_EVENT_RESET_COMPLETE..Driver reset is complete, link state stays
- * at LINK_DOWN. All PVCs are re-opened on

-* Abstract:
-* This is the interface for the basic functions that are provided by the OS.

-* DMW - Douglas M. Washabaugh
-* JAD - John A. Denisco
-* TLR - Theodore L. Ross
-*
-* Modification History:
-* Date Name Description
-* 08-Aug-94 DMW Created.
-* 04-Oct-94 DMW Changed ULONG to UINT32.
-* 19-Oct-94 TLR Added Simple List Utilities.
-* 26-Oct-94 TLR Updated Simple List Utilities based on review, retested.
-* 10-Nov-94 DMW Added the buffer descriptor and basic access macros.
-* 05-Dec-94 DMW Added an ALIGN macro.
-* 11-Jan-95 TLR Added utl_list_insert_after
-* 12-Jan-95 DMW Added MIN and MAX macros.
-* 18-Jan-95 JAD Moved BUFFER_DESCR and associated maros from here to
-* ss_ptsp.c (signaling module).
-* 22-Mar-95 TLR Added utl_buff_zero, utl_buff_copy, and utl_list_dealloc.
-* 23-Mar-95 DMW Changed name of utl_buff_zero and utl_buff_copy to
-* utl_mem_zero and utl_mem_copy to avoid confusion with
-* operating system buffers.
-*
-* Description:
-* This module contains general utility routines that are independent of the
-* operating system.
-*
-* Many of the functions deal with setting default values. This assists in
-* the situation that the caller has a value with several distinct fields,
-* all of which but one must be left with their "current" (default) values.
-* Without a helper routine, the caller should have to perform shifts, and
-* "and" operations.

-/* SIMPLE_LIST
- *
- * SIMPLE_LIST is a macro that creates a list of elements of a certain type.
- * The macro has two arguments:
- *
- * type - The data type for elements that will be stored in the list.
- * name - The name of the resulting list type.
- *
- * For a structure to be stored in a simple list, its first member must be a
- * pointer to that same kind of structure. For example, a list of names
- * would use a structure like the following:
- *
- * struct name_tag
- * {
- * struct name_tag *p_next;
- * char *text;
- * } NAME_RECORD;
- *
- * To create a type for a simple list of names, the following declaration
- * can be used:
- *
- * SIMPLE_LIST (NAME_RECORD, NAME_LIST);
- *
- * NAME_LIST is now a type for a list of elements of type NAME_RECORD. An
- * example of its usage is:
- *
- * NAME_LIST list_of_names;
- *

-* =============================
-* = utl_list_traverse (macro) =
-* =============================
-*
-* Overview:
-* Allows a simple list to be easily traversed. This macro is not in the
-* form of a function but in the form of a loop.
-*
-* Usage:
-* The utl_list_traverse macro should be used as a loop construct much like
-* a 'for' loop is used. utl_list_traverse must be followed by a statement
-* or bracketed group of statements. For example:
-*
-* NAME_LIST name_list;
-* NAME_RECORD *p_name_record;
-*
-* printf ("Names in the List:\n");
-* utl_list_traverse (name_list, p_name_record)
-* {
-* printf (" %s\n", p_name_record->text);
-* }
-*
-* Note that if the list is empty, the body of the loop will not execute.
-*
-* Do NOT use the utl_list_traverse macro to iteratively deallocate all of
-* the elements in the list! Use the utl_list_dealloc macro for this.
-*
-* Arguments:
-* list - (IN) The simple list to be traversed.
-*
-* p_index - (OUT) The loop index. This is a pointer to the structure stored
-* in the list. The loop executes once for each element
-* in the list and the p_index points to the element being
-* processed for each iteration.
-*
-* Returns:
-* Not Applicable
-*
-* Preconditions:
-* None
-*
-* Postconditions:
-* None

-*
-* Note that if the list elements contain pointers to allocated data, this
-* data will be lost. First use utl_list_traverse to deallocate all pointers
-* within the element structure. Use utl_list_dealloc to deallocate the
-* actual element structures within the list.
-*
-* Arguments:
-* os_handle - (IN) Handle of the appropriate utl_os instance.
-* list - (IN) Simple list to be cleared.

a set of LE servers.
.IP \fB\-i\ \fIinterface_number\fP
-Linux LEC supports up to 16 network interfaces. This number tells
-zeppelin to which of these to attach. Network interfaces are
-numbered from "lec0" to "lec15".
+Linux LEC supports up to 40+8 network interfaces. The interface_number
+tells zeppelin to which of these to attach. Ethernet type network
+interfaces are numbered from "lec0" to "lec39" and Token Ring
+interfaces are from "lec40" to "lec47". These parameters are tweakable
+during the kernel compile, see <linux/atmlec.h>.
.IP \fB\-t\ \fIMTU\fP

set the MTU of the LANE interface.

Enable proxy. When started with this option, it is possible to bridge
packets between ATM and Ethernet. That is, you can use LANE interfaces
with normal bridging. See the Bridging mini-Howto for more info.
+.IP \fB\-F\ \fIlogfile\fP
+Instead of writing debug messages to \fBstderr\fP, write the messages
+to the file \fBlogfile\fP. Use \fBsyslog\fP as the file name to use
+the \fBsyslog(3)\fP facility.
.IP \fB\-f\ \fIFore\ specific\ name\fP
The LANE servers on Fore ATM switches can display a special
name if a client can supply one. This name shows with command
\'conf lane les show advanced\'.
+.SH TOKEN RING CONSIDERATIONS
+A number of lec interfaces is reserved for Token Ring ELANs when the
+kernel is compiled with Token Ring (CONFIG_TR) support. See the
+discussion about interface_number command line option above. The Linux
+Token Ring LANE client does not support bridging between legacy Token
+Ring and ATM parts of the ELAN, so using the -p option is not
+recommended. Token Ring support has received less testing than its
+Ethernet counterpart.
.SH BUGS
-Supports only IEEE 802.3 / Ethernet type of ELANs. Please report any
-new bugs to Heikki Vatiainen <hessu@cs.tut.fi>

-.SH DESCRIPTION
-A LAN Emulation Client is an entity in an ATM endstation that performs
-data forwarding, address resolution and other control functions. It
-uses the LUNI interface when communicating with other components in
-emulated LANs. It provides upper protocol layers a MAC like
-interface similar to IEEE 802.3/Ethernet or IEEE 802.5/Token Ring LAN.
-.PP
-LAN Emulation client code is divided into two parts: user space
-application LAN Emulation Demon called (LED) \fBzeppelin(8)\fP, and the
-kernel component. \fBZeppelin\fP is responsible for control operations needed
-in LAN Emulation clienthood. It forms the necessary VCCs and receives
-all the LE control frames and acts accordingly. It also controls the
-operation of the LEC kernel component.
-.PP
-Linux LEC supports only Ethernet type of emulated LAN.
-.PP
-\fBSIGHUP\fP causes restart of the LEC. All resources are
-released and \fBzeppelin\fP is started.
-.SH OPTIONS
-.IP \fB\-c\ \fILECS_address\fP
-ATM address of \fBlecs(8)\fP (Lan Emulation Configuration Server), if not
-set, Well-Known server address is used.
-.IP \fB\-s\ \fILES_address\fP
-ATM address of \fBles(8)\fP (Lan Emulation Server), can be used in
-bypassing configuration phase in joining emulated Lan i.e \fBlecs\fP address
-is not used.
-.IP \fB\-e\ \fIesi\fP
-Mac address to use when communicating in Emulated LAN. E.g. 00:20:22:23:04:05 .
-.IP \fB\-n\ \fIVLAN_name\fP
-Name of the virtual LAN to which joining is requested.
-This is used in LE_CONFIGURE_REQUEST to LECS or
-LE_JOIN_RESPONSE to LES, if configuration phase is bypassed.
-.IP \fB\-m\ \fImesg_mask\fP
-Sometimes one wants to know more what is happening in LE
-daemon e.g. when nothing works. This is a hexadecimal long value
-setting global message mask. 0 = No messages, ffff = All messages.
-.IP \fB\-l\ \fIlisten_address\fP
-Local ATM address that zeppelin uses as local binding point in
-signalling. Use this if you are running more than one client or
-a set of LE servers.
-.IP \fB\-i\ \fIinterface_number\fP
-Linux LEC supports up to 16 network interfaces. This number tells
-zeppelin to which of these to attach. Network interfaces are
-numbered from "lec0" to "lec15".
-.IP \fB\-t\ \fIMTU\fP
-The MTU of ELAN to join. You need to also use \fBifconfig(8)\fP to
-set the MTU of the LANE interface.
-.IP \fB\-1\fP
-Run as LANEv1 client. This is the default.
-.IP \fB\-2\fP
-Run as LANEv2 client. This is required by MPOA.
-.IP \fB\-p\fP
-Enable proxy. When started with this option, it is possible to bridge
-packets between ATM and Ethernet. That is, you can use LANE interfaces
-with normal bridging. See the Bridging mini-Howto for more info.
-.IP \fB\-F\ \fIlogfile\fP
-Instead of writing debug messages to \fBstderr\fP, write the messages
-to the file \fBlogfile\fP. Use \fBsyslog\fP as the file name to use
-the \fBsyslog(3)\fP facility.
-.IP \fB\-f\ \fIFore\ specific\ name\fP
-The LANE servers on Fore ATM switches can display a special
-name if a client can supply one. This name shows with command
-\'conf lane les show advanced\'.
-.SH BUGS
-Supports only IEEE 802.3 / Ethernet type of ELANs. Please report any
-new bugs to Heikki Vatiainen <hessu@cs.tut.fi>
-.PP
-John Bonham died 1980 and Led Zeppelin broke.
