* Modification history
*
* Revision 2.16 1993/11/29 16:55:56 davidg
* merged in Garrett Wollman's strict prototype changes
*
* Revision 2.15 1993/11/29 16:32:58 davidg
* From Thomas Sandford <t.d.g.sandford@comp.brad.ac.uk>
* Add support for the 8013W board type
*
* Revision 2.14 1993/11/22 10:55:30 davidg
* change all splnet's to splimp's
*
* Revision 2.13 1993/11/22 10:53:52 davidg
* patch to add support for SMC8216 (Elite-Ultra) boards
* from Glen H. Lowe
*
* Revision 2.12 1993/11/07 18:04:13 davidg
* fix from Garrett Wollman:
* add a return(0) at the end of ed_probe so that if the various device
* specific probes fail that we just don't fall of the end of the function.
*
* Revision 2.11 1993/10/23 04:21:03 davidg
* Novell probe changed to be invasive because of too many complaints
* about some clone boards not being reset properly and thus not
* found on a warmboot. Yuck.
*
* Revision 2.10 1993/10/23 04:07:12 davidg
* increment output errors if the device times out (done via watchdog)
*
* Revision 2.9 1993/10/23 04:01:45 davidg
* increment input error counter if a packet with a bad length is
* detected.
*
* Revision 2.8 1993/10/15 10:59:56 davidg
* increase maximum time to wait for transmit DMA to complete to 120us.
* call ed_reset() if the time limit is reached instead of trying
* to abort the remote DMA.
*
* Revision 2.7 1993/10/15 10:49:10 davidg
* minor change to way the mbuf pointer temp variable is assigned in
* ed_start (slightly improves code readability)
*
* Revision 2.6 93/10/02 01:12:20 davidg
* use ETHER_ADDR_LEN in NE probe rather than '6'.
*
* Revision 2.5 93/09/30 17:44:14 davidg
* patch from vak@zebub.msk.su (Serge V.Vakulenko) to work around
* a hardware bug in cheap WD clone boards where the PROM checksum
* byte is always zero
*
* Revision 2.4 93/09/29 21:24:30 davidg
* Added software NIC reset in NE probe to work around a problem
* with some NE boards where the 8390 doesn't reset properly on
* power-up. Remove initialization of IMR/ISR in the NE probe
* because this is inherent in the reset.
*
* Revision 2.3 93/09/29 15:10:16 davidg
* credit Charles Hannum
*
* Revision 2.2 93/09/29 13:23:25 davidg
* added no multi-buffer override for 3c503
*
* Revision 2.1 93/09/29 12:32:12 davidg
* changed multi-buffer count for 16bit 3c503's from 5 to 2 after
* noticing that the transmitter becomes idle because of so many
* packets to load.
*
* Revision 2.0 93/09/29 00:00:19 davidg
* many changes, rewrites, additions, etc. Now supports the
* NE1000, NE2000, WD8003, WD8013, 3C503, 16bit 3C503, and
* a variety of similar clones. 16bit 3c503 now does multi
* transmit buffers. Nearly every part of the driver has
* changed in some way since rev 1.30.
*
* Revision 1.1 93/06/14 22:21:24 davidg
* Beta release of device driver for SMC/WD80x3 and 3C503 ethernet boards.

* Revision 2.6 93/10/02 01:12:20 davidg
* use ETHER_ADDR_LEN in NE probe rather than '6'.
*
* Revision 2.5 93/09/30 17:44:14 davidg
* patch from vak@zebub.msk.su (Serge V.Vakulenko) to work around
* a hardware bug in cheap WD clone boards where the PROM checksum
* byte is always zero
*
* Revision 2.4 93/09/29 21:24:30 davidg
* Added software NIC reset in NE probe to work around a problem
* with some NE boards where the 8390 doesn't reset properly on
* power-up. Remove initialization of IMR/ISR in the NE probe
* because this is inherent in the reset.
*
* Revision 2.3 93/09/29 15:10:16 davidg
* credit Charles Hannum
*
* Revision 2.2 93/09/29 13:23:25 davidg
* added no multi-buffer override for 3c503
*
* Revision 2.1 93/09/29 12:32:12 davidg
* changed multi-buffer count for 16bit 3c503's from 5 to 2 after
* noticing that the transmitter becomes idle because of so many
* packets to load.
*
* Revision 2.0 93/09/29 00:00:19 davidg
* many changes, rewrites, additions, etc. Now supports the
* NE1000, NE2000, WD8003, WD8013, 3C503, 16bit 3C503, and
* a variety of similar clones. 16bit 3c503 now does multi
* transmit buffers. Nearly every part of the driver has
* changed in some way since rev 1.30.
*
* Revision 1.1 93/06/14 22:21:24 davidg
* Beta release of device driver for SMC/WD80x3 and 3C503 ethernet boards.
*
