Hi Manfred,

I filed BUG 6480 describing the problem and providing lots
of info. If you need more info, just ask.

At the moment I have no idea about the reasons.
Except Crossover-Cabling vs. using a switch.

The machine is a production machine, so I cannot test
kernels and patches. 

But I have several machines with identical hardware where
I can test this.

Once we can reproduce it without a Sonicwall, I can build a 
test setup using any kernel hackery required to resolve the issue :-)

Could you please contact the right nVIDIA people, if needed?

PS: Stephen, you are not CC'ed from bugzilla and 
      "agreed to help out with net driver maintenance" 
       so I CC'ed you here manually.

Regards

Ingo Oeser

Has anyone looked into making this driver use NAPI?  This would fix
the IRQ overload problem and a number of other DoS risks.
Also, if done right the device lock could be reduced to just
a transmit lock.

Making it support netpoll would be nice too.

<wishlist>
Disable/resume the device with something less gross than
