[tulip] Netgear PNIC Stops working after cable disconnect

[James Zhu]

Well, I still have problems w/ Netgear FX310-TX cards using the latest
tulip.c (v0.93).

The card stops working after disconnecting and reconnecting the Ethernet
cable. I know many other has experienced this problem in the past....

I have this problem w/ all tulip drivers from 2.2.14-19 kernel tree.... So I
tried Don's v0.93. same symptoms.

Before the unplug the cable. tulip-diag report the card is happy in
100BaseTX mode, Port selection is MII, full duplex. The recv is "idle", and
transmit is "waiting to transmit".

After unplugging then plugging the cable, tulip-diag reports the port
selection is 10mpbs-serial, half duplex. Both xmit and recv are in "stopped"
state. I couldn't get them to restart. I tried "-R", "-F many_types"...

I don't have problem w/ tulip.c from 2.2.12 kernel tree, but that driver
hangs after a long session of stress test. (ie. overnight).... for that I am
looking for alternatives... but all new tulip driver I tried so far has this
disconnect problem.... Am I the only one seeing this?

Here is the output of tulip-diag -mm, when the driver hangs:
