You can look at the archives for netdev at oss.sgi.com (look for the
"Advice needed on IP-over-InfiniBand driver" thread) to see the full
exchange.  The basic idea is that we need to teach the Linux
networking core about the fact that IPoIB needs a second path record
lookup after the ARP/ND, and that the layer 2 header is built by the
HCA rather than the network driver.
