[tulip] autonegotation problems with 21143

[alvin]

I am running a UP1100 with an integrated 21142/3 NIC.

I seem to be having some problems with autonegoation. The kernel is a
more or less stock RH 2.2.19-6.2.1

the following is from my dmesg listing.

eth0: Digital DS21143 Tulip rev 65 at 0x10100, 00:00:F0:51:00:EB, IRQ 5.

eth0: Using NWay-set 100baseTx-FD media, csr12 45e1d2cc.
eth0: Transmit error, Tx status 7fffb200.


If I let the driver autonegotate I get a large number of transmit
errors. If I set the options=5 and try to force 100MB-FDX then I get the
following recieve errors

eth0: 21143 negotiation status 000002c0, 100baseTx-FD.
eth0: Receive error, Rx status 00468326.
eth0: Receive error, Rx status 004a8322.
eth0: Receive error, Rx status 004c8326.
eth0: Receive error, Rx status 00568326.
eth0: Receive error, Rx status 004a8326.
eth0: Receive error, Rx status 004c8322.
eth0: Receive error, Rx status 00428322.
eth0: Receive error, Rx status 005b8326.

Any pointers or suggestions would be greatly appreciated.
