Re: [PATCH] RDMA/CMA: Use neigh_event_send() to initiate neighbour discovery.

Once this is applied upstream, I can pull it back in to ofed-1.2.5 and ofed-1.3.

Calling arp_send() to initiate neighbour discovery (ND) doesn't do the
full ND protocol.  Namely, it doesn't handle retransmitting the arp
request if it is dropped. The function neigh_event_send() does all this.
Without doing full ND, rdma address resolution fails in the presence of
dropped arp bcast packets.
