Well, it currently supports TCP as the sole underlying transport so
it'll run over anything TCP does, including IPoIB :)

It's my next priority after getting the TCP support stable.  That's
nearing completion, so I'll probably start on the IB side in a small
number of weeks.

This version of the RDS socket API doesn't expose RDMA support to
applications.  sendmsg() and recvmsg() copy for now.  The plan is to
support zero copy, async operations, and direct data placement at some
point in the future but the specifics haven't been decided.

Yes, link fail-over will be supported in the upcoming IB transport.
