I agree.

Clearly following the model of IB is the best way to fit this in
without major changing. RDMA-CM is the way to get IP integration, it
uses existing eth devices attached to the master eth device (analogous
to IPoIB devices) and resolves IP to eth device to VLAN header and
neighbour.

If someone needs to do something else special it is pretty easy to do
all the same steps in userspace using netlink, and that could go into
a library, just like PR queries for IB.
