Hi,
I've recently upgraded a router which has three 3Com900C Tornado cards
revisions 74 and 78 from Linux 2.4 to 2.6.
IIRC, Linux 2.4 allowed to report if the link beat was sensed to be 10
or 100 mbps, Linux 2.6 does not. One of these cards is attached to
peculiar network gear and needs to be forced to 100baseTx-FD.
I configured options=0x204 for that interface, which sorta worked;
vortex-diag and mii-diag still report autonegotiation were enabled.
Strange.
ethtool (I tried v2 and v3) does not appear to work at all for 3C900C
cards, "No data available" if run without options.
Any insight into these would be appreciated,

In 2.6.11 ethtool data should be available. Please let me know if
you are using 2.6.11 and ethtool does not work with your card.
I have no Tornado card to test but with 3c905/3c905B cards and
options=0x204 configured, mii-diag reports:
Auto-negotiation disabled, with Speed fixed at 100 mbps, full-duplex.
I suppose you talking about 3c905C Tornado cards
(3c900 cards are not of Tornado type).

Ouch. Yes indeed, 3C905C. Please excuse my spreading confusion here.
(I also have 3C900 Combo here, these are Boomerang cards.)
I'll try 2.6.11 as workload permits, the machine is a router in
production with SuSE 9.2 (2.6.8 + SuSE hacks, "2.6.8-24.11-default")
kernel.
