eth0: ADMtek Centaur-P rev 17 at 0xd0046000, 45:BA:45:BA:45:BA, IRQ 15.
eth0:  MII transceiver #1 config 3000 status 786d advertising 01e1.

    Is that what this is? If so, I'd be glad to help test. At
    present, all I can do is ping other hosts (and they can ping
    this box.) I have not successfully started any TCP connections.
    Based on the LEDs on my router and counters visible in
    /proc/net/dev, the other hosts are trying to respond, but the
    incoming messages just don't seem to get recognized.

    (I've ruled out network configuration problems by removing this
    card and reinstalling an older Linksys "EtherPCI" (21041-AA)
    card and (with the stock driver that comes with 2.2.17) all is
    almost well. (transferring large files between machines went
    at about 200KB/s and there were lots of errors.)

    many thanks,
