This patch fixes the problem by checking for a valid netdev pointer
before using it to get the port MAC address.

just curious, how did you actually stepped on this, code inspection or
any actual race?

Or.

I hit the problem during error recovery after injecting an EEH error on
a distro kernel based on linux 3.0. I was not able to reproduce the
problem on the mainline kernel, but it seems to be just a matter of
having the right timing.
