Remaining Problems:
1. Serialization of access to variables in the llc structure
by mac_data_indicate(), timer expired functions, and data_request() .
There is not serialization of any kind right now.
While testing, I have not seen any problems that stem from this lack of
serialization, but it wories me...
2. The code is currently able to handle one connection only,
there is more work in register_cl2llc_client() to make a chain
of llc structures and in mac_data_indicate() to find back
the llc structure addressed by an incoming frame.
According to IEEE, connections are identified by (remote mac + local mac
+ dsap + ssap). dsap and ssap do not seem important: existing applications
always use the same dsap/ssap. Its probably sufficient to index on
the remote mac only.
3. There is no test to see if the transmit window is full in data_request()
as described in the doc p73, "7.5.1 Sending I PDUs" 3th alinea.
The pdus presented to data_request() could probably go on the
awaiting-transmit-queue (atq). The real difficulty is coding a test
to see if the transmit window is used up and to send the queue
when space in the window becomes available.
As I have no network layer that can generate a continous flow of pdus it is
difficult to simulate a remote busy condition and hence to test the code
to handle it.
4. A simple flow control algorithm, steering the size of the transmit
window would be nice to have.

CONFIG_SPX
* Orphaned entry retained 20 April 2001 by Petr Vandrovec *
* If you read this note from the configurator, please contact *
* the Configure.help maintainers. *
The Sequenced Packet eXchange protocol is a transport layer protocol
built on top of IPX. It is used in Novell NetWare systems for
client-server applications and is similar to TCP (which runs on top
of IP).
Note that Novell NetWare file sharing does not use SPX; it uses a
protocol called NCP, for which separate Linux support is available
("NCP file system support" below for the client side, and the user
space programs lwared or mars_nwe for the server side).
Say Y here if you have use for SPX; read the IPX-HOWTO at
<http://www.linuxdoc.org/docs.html#howto> for details.
This driver is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called af_spx.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.

* This module implements the (SPP-derived) Sequenced Packet eXchange
* (SPX) protocol for Linux 2.1.X as specified in
* NetWare SPX Services Specification, Semantics and API
* Revision: 1.00
* Revision Date: February 9, 1993
*
* Developers:
* Jay Schulist <jschlst@samba.org>
* Jim Freeman <jfree@caldera.com>
* Arnaldo Carvalho de Melo <acme@conectiva.com.br>
*
* Changes:
* Alan Cox : Fixed an skb_unshare check for NULL
* that crashed it under load. Renamed and
* made static the ipx ops. Removed the hack
* ipx methods interface. Dropped AF_SPX - its
* the wrong abstraction.
* Eduardo Trapani : Added a check for the return value of
* ipx_if_offset that crashed sock_alloc_send_skb.
* Added spx_datagram_poll() so that select()
* works now on SPX sockets. Added updating
* of the alloc count to follow rmt_seq.
* Arnaldo C. Melo : Use a private slabcache for the old tp_pinfo
* struct sock member, use spx_sk and ipx_sk
* Arnaldo C. Melo : Big CodingStyle cleanup, fixes some lock leaks,
* removes a leftover of the slabcache patch.
