[vortex] Problem with 3c905b under 2.2.16

[Shane Wegner]

Hi all,

This system, a pentium 75 with 8mb of ram, locks the network when another
system, a pentium 233 with 128mb ram blasts UDP trafic at it.  The p75 does
not seem to be affected when TCP trafic is used.  The following shows up in
dmesg when using debug with the vortex module.

and upon bringing the interface down.

eth0: vortex_close() status e000, Tx status 00.
eth0: vortex close stats: rx_nocopy 77860 rx_copy 33 tx_queued 14 Rx
pre-checksummed 0.

Bringing eth0 down then back up again corrects the problem until a lot of
UDP trafic is sent.  The UDP packets are being sent with ttcp at 100mbps. 
Any suggestions on how I could correct this problem would be greatly
appreciated.
Cheers,
Shane
