[ofa-general] mapping IP addresses to GIDs across IP subnets

[Max Matveev]

IB GID has the same format as IPv6 address, IPv6 addresses are
resolvable via DNS' AAAA or A6 records, you can go from IPv4 to name
to IPv6 address without reinventing the wheel.

It would not help with replacing arp use in rdma_cm though.
