So I did a little local experimentation; I didn't run into the precise
problem you saw, instead getting ENOBUFS on sending.  I think compiled
"device vlan" into the kernel to make debugging easier, and the problem
magically vanished.  I'm going to keep trying to reproduce it, but for
grins, could you tell me if you're running with vlan support compiled in
or loaded, and if loaded, try compiling it in?
