sounds OK by me. You should get an opinion from people who 
know the code better than I do.

I assume the function is there

o to speed up LVS (useful but not required for LVS-NAT)

o to push the layer 2 packet for LVS-DR out on the wire. 
This packet has the MAC address of the RIP, but 
dst_addr=VIP, so can't be sent through routing.
