[2.6.0] autonegotiation broken with 3c905C
On Linux 2.6.0 (and earler -test versions), the card is stuck in 10-BaseT half-duplex mode, at least according to mii-tool. The abysmal TCP performance for bulk transfers *from* that host suggests that it's true. 8-(
Boot messages are:

"lspci -v" shows the following output:

Any suggestions?
(The card is fine with 2.4.21.)

grr, someone should fix this.
Could you please gather all the info which is described in Documentation/networking/vortex.txt under both 2.4 and 2.6 and send it to me? I'll see if I can remember how the darn thing works.
Thanks.
