Problems with tulip driver with lite-on -- transmit timed out

[John Ruttenberg]

I'm not sure exactly when this problem was introduced, but I'm pretty sure it
didn't exist in the 2.2.x kernels.  It does exist in the 2.4.0-test12, 2.4.0,
and 2.4.1 kernels.

Any high bandwidth sustained inward transfer seems to hang up the card after a
little while (< 1 minute with ftp, longer with nfs).  Once the card hangs,
the syslog has entries:

    NETDEV WATCHDOG: eth0: transmit timed out

cancelling the inward ftp and restarting the network unwedges the problem.

Here is what's in my /proc/pci for the nic:

    Bus  0, device  12, function  0:
       Ethernet controller: Lite-On Communications Inc LNE100TX (rev 32).
         IRQ 11.

There seems to have been some relevant LKML traffic on the topic, but I
couldn't decipher it in terms of what it means to me.

I'm not subscribed to lkml, so please cc me in replies.

Thanks in advance for any help.
