This does seem neater, but I don't know how to implement it. How does
one hook into ARP events?

ARP works because we can send broadcasts even without a path to a
specific destination. (I'm leaving out the details of how IP
broadcast gets mapped to InfiniBand multicast) When the system with
the IP we're looking for receives a broadcast ARP, it can use the HW
address in the ARP request to look up a path, so it can send an ARP
reply.
Thanks,
Roland
