+1.  A single shared upstream (with all transports and all the vendors'
drivers) is the best possible upstream in this case.

We do have a couple of FreeBSD-specific changes in the iWARP bits
(unify_tcp_port_space always 1, and some changes to the listener in the
iWARP CM) but they have been easy to maintain so far.
