Reduce the number of dst_get_neighbour_noref() calls within a single call chain. Primarily by passing the neighbour pointer down to the helper functions. Handle dst_get_neighbour_noref() returning NULL in ipoib_start_xmit() by incrementing the dropped counter and freeing the packet. We don't want it to fall through into the ARP/RARP/multicast handling, since that should only happen when skb_dst() is NULL. Signed-off-by: David S.
