Anthony:
This is already addressed by VMDq solution(or so called netchannel2),
right? Qing He is debugging the KVM side patch and pretty much close to end.
For this single purpose, we don't need SR-IOV. BTW at least Intel
SR-IOV NIC also supports VMDq, so you can achieve this by simply use "native"
VMDq enabled driver here, plus the work we are debugging now.
Thx, eddie
