Since 2.6.8, I've noticed that the tigon3 support has problems on PPC machines.

I have a group of powerpc machines (PowerMac G4) whith an extra tigon3
compatible network card, a 3c996 from 3Com.

They are connected to a 3com Gigabit switch and with kernel version 2.6.7 they
are working fine.

Since 2.6.8, then 2.6.9 and now 2.6.10, they are not working as expected. They
lost connection, many times with this message

Disconnecting: Corrupted MAC on input.
lost connection

Linux version 2.6.10-rc3fcdyc-ppc (root@afs02-i) (gcc versión 3.3.4 (Debian
1:3.3.4-13)) #1 Fri Dec 24 08:46:32 CET 2004

I'm working with debian sarge and I've noticed this problem with kernel from
kernel.org and the debianized packages.
The machines are PowerMac G4 (Silver) with 256MB Ram, 733MHz Processor, no
cd-rom, a 3c996 Gigabit tigon3 compatible network card.

If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.
