In the function rxe_init_packet, based on av->network_type,
skb->protocol is set to ipv4 or ipv6. The functions rxe_prepare
and rxe_send are called after the functin rxe_init_packet.
So in these functions, av->network_type can be replaced with
skb->protocol.
The functions are in the xmit fast path. So with skb->protocol,
the performance will be better.

It doesn't compile, please rebase and resend:
drivers/infiniband/sw/rxe/rxe_net.c: In function ‘rxe_prepare’:
drivers/infiniband/sw/rxe/rxe_net.c:403:43: error: ‘av’ undeclared (first use in this function)
if (ether_addr_equal(skb->dev->dev_addr, av->dmac))
OK. I will resend a new patch ASAP. Please wait.
