[2.6.0] autonegotiation broken with 3c905C

[2.6.0] autonegotiation broken with 3c905C

[Florian Weimer]

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:

kernel: 3c59x: Donald Becker and others. www.scyld.com/network/vortex.html
kernel: 0000:00:08.0: 3Com PCI 3c905C Tornado at 0xd000. Vers LK1.1.19

"lspci -v" shows the following output:

00:08.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 30)
        Subsystem: 3Com Corporation 3C905C-TX Fast Etherlink for PC Management NIC
        Flags: bus master, medium devsel, latency 32, IRQ 11
        I/O ports at d000 [size=128]
        Memory at e3000000 (32-bit, non-prefetchable) [size=128]
        Expansion ROM at <unassigned> [disabled] [size=128K]
        Capabilities: [dc] Power Management version 2

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.
