Re: Advice needed on IP-over-InfiniBand driver

["David S. Miller" <davem@xxxxxxxxxxxxx>]

You probably want to be editing net/ipv4/arp.c and testing
it about Infiniband.  Keep neighbour entries in the unresolved
stated until both transitions are made:

1) obtain 20 byte address
2) get response from IB subnet manager

Only store the destination GID in the neighbour entry,
and only mark the neighbour entry as resolved once
#2 above completes successfully.
