I can, with and without that patch.

But I encounter problems bringing the interface back up and down again. 
If I do the following after a reboot:

   /etc/init.d/network stop
   /etc/init.d/network start
   /etc/init.d/network stop

I find that the "ip link set dev eth0 down" command hangs, consuming 
most of the CPU time (~99%). Note that I issued the "network" commands 
with about a second's delay between each command.

This is with a static IP address. If the IP address is assigned via 
DHCP, then the DHCP client hangs in the "network start" command.

I'm running Fedora Core 3 + all the latest security updates.

That sounds good.

I'm happy to submit a patch to do this, if you'd like. Note that I'm new 
to kernel programming, so it might take me a while.

Bye, Rich =]
