>Description:
Version 2 of this PCMCIA card is incorrectly identified as a NE2000,
and the incorrect MAC address is extracted.
ed0: address 01:d4:ff:03:00:20, type NE2000 (16 bit)
The MAC address should be 00:e0:98:80:15:df (as printed on the card
and reported by Windoze).
>How-To-Repeat:
>Fix:
/sys/dev/ed/if_ed.c:ed_probe_Novell_generic tries to identify if the
card is NE2000, NE1000, or Linksys by writing a test pattern into
the card's memory at 8k. This fails for the V2 version of the
Linksys PCMPC100, so ed_get_Linksys doesn't get called to extract
the MAC address in the special way needed for the Linksys (DL10019C).
When I change that conditional in if_ed.c to always succeed,
=================================================================

ed_pio_writemem(sc, test_pattern, 8192, sizeof(test_pattern));
ed_pio_readmem(sc, 8192, test_buffer, sizeof(test_pattern));
! if (bcmp(test_pattern, test_buffer, sizeof(test_pattern)) == 0) {
/* could be either an NE1000 or a Linksys ethernet controller */
linksys = ed_get_Linksys(sc);
if (linksys) {

! /*if (bcmp(test_pattern, test_buffer, sizeof(test_pattern)) == 0) {*/
! if (1) {
/* could be either an NE1000 or a Linksys ethernet controller */
linksys = ed_get_Linksys(sc);
if (linksys) {
=================================================================
the correct MAC address is not extracted and the card is
identified as a "Linksys" instead of a "NE2000".
ed0: address 00:e0:98:80:15:df, type Linksys (16 bit)
Note that I'm not suggesting the above diff as the fix, but it
does point out where the driver needs to be fixed.
