This code is heavily based on the linux driver as written by

Russell Nelson <nelson@crynwr.com> and Donald Becker

<becker@cesdis.gsfc.nasa.gov> and modified by Mike Cruse
|
||||
<mcruse@cti-ltd.com>. That driver has been released under the

conditions of the GNU Public License, thus this one is probably to
|
||||
be considered "derived work". Therefore, there are some legal
|
||||
obstacles in combining this file with etherboot's code, which is
|
||||
released under a BSD style license.
|
||||
Permission is granted to distribute the enclosed cs89x0.[ch] driver
|
||||
only in conjunction with the Etherboot package. The code is
|
||||
ordinarily distributed under the GPL.
|
||||
|
||||
So, if you want to actually use this code, you should make sure that
|
||||
you are aware of the legal implications. I release *my* work into
|
||||
the PUBLIC DOMAIN which implies that you can use it either under a
|
||||
BSD style license, or under the conditions of the GPL, or under any
|
||||
other conditions that you like. N.B. this does not apply to the
|
||||
parts that originate from other authors. So, you should probably
|
||||
contact them first and verify if they agree with your intended use.
|
||||
|
||||
If you contacted all of the above authors and they agreed to give
|
||||
special permission for using this code under the conditions of a BSD

Shuffled things around, removed the leftovers from the 8129 support

that was in the Linux driver and added a bit more 8139 definitions.

Moved the 8K receive buffer to a fixed, available address outside the

0x98000-0x9ffff range. This is a bit of a hack, but currently the only

way to make room for the Etherboot features that need substantial amounts

of code like the ANSI console support. Currently the buffer is just below
|
||||
0x10000, so this even conforms to the tagged boot image specification,
|
||||
which reserves the ranges 0x00000-0x10000 and 0x98000-0xA0000. My
|
||||
interpretation of this "reserved" is that Etherboot may do whatever it
|
||||
likes, as long as its environment is kept intact (like the BIOS
|
||||
variables). Hopefully fixed rtl_poll() once and for all. The symptoms
|
||||
were that if Etherboot was left at the boot menu for several minutes, the
|
||||
first eth_poll failed. Seems like I am the only person who does this.
|
||||
First of all I fixed the debugging code and then set out for a long bug
|
||||
hunting session. It took me about a week full time work - poking around
|
||||
various places in the driver, reading Don Becker's and Jeff Garzik's Linux
|
||||
driver and even the FreeBSD driver (what a piece of crap!) - and
|
||||
eventually spotted the nasty thing: the transmit routine was acknowledging
|
||||
each and every interrupt pending, including the RxOverrun and RxFIFIOver
|
||||
interrupts. This confused the RTL8139 thoroughly. It destroyed the
|
||||
Rx ring contents by dumping the 2K FIFO contents right where we wanted to
|
||||
get the next packet. Oh well, what fun.
|
||||
|
||||
18 Jan 2000 mdc@thinguin.org (Marty Connor)
|
||||
Drastically simplified error handling. Basically, if any error
|
||||
in transmission or reception occurs, the card is reset.
