I forgot to mention my kernel conf.... I'm not sure if it would cause this
issue, but I'll test again with GENERIC.

 The interface is just dead after creating the vf's earlier. Recreating
with only 2, its still dead.

Running out of ideas, decided to try a tcpdump...

I don't think this is that helpful tho. =/
tcpdump on the other end, the packets are never received.

I'v already double checked VT-d, but I'll make it tripple! =] I can't reset
the system right now, but ill send an update when possible with only 2 vf's
and unmodified generic.
