Right, there should only be one route lookup call. And the send_arp should
match what TCP/UDP are doing, I'm pretty sure they don't use neigh_event_send
like ib_addr is, or if they do, they are not using ip_route_output_key to get
the neighbor entry. I could not find the code that generates arps for these
protocols.
They do, but indirectly, dst_output() cals neigh_resolve_output()
which calls neigh_event_send() - since there is no real skb in the RDMA
routines it seems reasonable to call neigh_event_sent() directly..
ip_route_output_key is used to populate dst in the skb which is
fetched by neigh_resolve_output to get the neigh and the neigh has the
ofid.
