OK, I'm curious about the results.

OK.

I doubt about autonegotiation, as the MII data that is necessary is not
present, so no driver can read it!
If the suggestions using mii-diag do not give any good results, read
below.

Yes, maybe the Windows driver is falling back to a fixed speed mode. If I
understand it right, the Linux driver does not change from autonegotiation
(NWAY) to anything else. In this case, forcing media type as module
options is the only way to set it. You can use "options=4" for setting
100baseTx (more at http://www.scyld.com/network/vortex.html)

Hope this helps!
