yeah. :^(
Rules out those two theories pretty much.

Definitely not compatible.

And as noted in the previous email, I don't advise ifdown the NIC
unless you can verify it will not corrupt the memory that was
previously used for RX descriptors and RX buffers.

OTOH, 100BT cards are *so* cheap, it should be possible to replace
if it's not built-in on the motherboard.

Sorry for the bad news and thanks for doing the extra tests.

But still, I'm hopeing for two code changes as a result:
1) include CSR5 and CSR6 in the printk output
2) the date of the tulip driver revision needs to be updated (or dropped).

thanks,
grant
