Subject: [PATCH 3/3] infiniband: nes: Convert nes_addr_resolve_neigh() over to dst_neigh_lookup().
Date: Tue, 24 Jan 2012 18:16:03 -0500 (EST) [thread overview]
Message-ID: <20120124.181603.2050827731650521325.davem@davemloft.net> (raw)
Now we must provide the IP destination address, and a reference has
to be dropped when we're done with the entry.
