[vortex] 3c905CX-TXM

Hi,

I recently bought several OEM 3Com NICs. The stickers on the bubble-wrap 
said they're 3C980TX, on the cards themselves the model id is given as
3c905CX-TXM.

I haven't been able to get them working so far. The driver loads fine, 
I can bring up the eth device, but the network remains unreachable.
The MII transceivers have status 0x0020 which makes me think that things
don't progress beyond the negotiation step.

I have other 3Com cards on the network -- 3c905C-TX [Fast Etherlink] 
(rev 74) as reported by lspci -- which work fine, so it's probably not 
a network/cabling problem.

I'm including some diagnostics below (vortex-diag/mii-diag output among
others); they will surely make more sense to some of you than this humble
user. At the end of the mail, you can also find debug messages produced
by 3Com's 3c90x driver (which fails at the ifconfig stage).

I'd really appreciate any comments/suggestions.

Cheers,

Berkan
