* 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 2.2 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.
time conversion in delay().
fd.c: Minor changes to autoconfig. Use dv_parent rather than storing another
pointer to the fdc_softc in each fd_softc. Change disk label stuff for our
kernel.
icu.s: Make splx() and splnone() return previous cpl for now.
isa.c: Minor autoconfig changes.
isa.h: rtcin() is now nvram() and is declare in nvram.h. Make isaphysmem a
caddr_t.
pccons.c: XXXX: Maybe we should insist they open /dev/io now.
timerreg.h: #define TIMER_NPORTS.
wd.c: Delete unused wdnoreloc() and wddospart(), and use remaining two bits in
unit number. struct disk --> struct wd_softc. struct board --> struct
wdc_softc. Still needs much work.
1) fixed 3c503 lock-up if the thinwire cable was disconnected at boot time
2) 8013EBT boards now work (quite well!) in 16bit/16k mode
3) ED_NO_DOUBLE_BUFFERING flag now works
4) slightly higer performance (about 3%) with 16bit WD/SMC boards
5) support for WD8013WC (10BaseT) boards
Additionally, the probe code has been reorganized to be much cleaner. This
revision of the driver is 1.25. The release notes have been updated as well.
(1) added support for ed1 in both generic kernels at:
device ed1 at isa? port 0x250 net irq 9 iomem 0xd8000 vector edintr
(2) brought if_ed.c up to DG's 1.19 rev.
