OK, here what was happening: kernel was seeing one extra card !!! eth0
was the BMAC, eth1 was a GHOST ethernet interface, and then after
manually doing 'modprobe tulip' the kernel would register yet another
eth interface - eth2.
eth2 WORKS!
Here is what was going on, maybe some of you can explain it to me:
early in the boot process-
Mar 30 19:09:50 cosray-g3 kernel: eth0: BMAC at 00:05:02:ad:d9:22
Mar 30 19:09:50 cosray-g3 kernel: eth1: DC21143 at 0x0400 (PCI bus 0,
device 14)
, h/w address 00:00:c5:53:b4:a1,
Mar 30 19:09:50 cosray-g3 kernel: and requires IRQ24 (provided by
PCI BIOS
).
Mar 30 19:09:50 cosray-g3 kernel: de4x5.c:V0.544 1999/5/8

OK. eth1 does not work after this.
Now I do 'modprobe tulip' -

And eth2 interface is created. Now I do 'ifup eth2' and bingo, it
works!!!
here is the result - ifconfig gives me
eth2 Link encap:Ethernet HWaddr 00:00:C5:53:B4:A1
inet addr:128.175.14.23 Bcast:128.175.14.255

RX packets:0 errors:0 dropped:0 overruns:0 frame:0

Which is fine. Telnet works, ping works.
Would somebody explain to me what exactly was going on?
Thanks.
