Hi,

i'm working on kgdb for linux-2.6, and added netpoll support to the
lasi_82596 driver. Maybe we can add this patch?

Thanks, maybe one day this will be useful for kgdb debugging over
ethernet - but this needs some work, at the Moment there are no
breakpoints and no singlestepping in my kgdb port for linux-2.6.

Bye,

Sven
