RDMA support on FreeBSD



Chelsio's T3 card supports iWARP (RDMA over TCP). I've ported
OpenFabric's kernel infrastructure for supporting RDMA to FreeBSD. Do
we think that other RDMA providers (IB or iWARP) will be interested
in supporting FreeBSD? If so it makes sense to put it under
sys/contrib/rdma, otherwise I'll just add it as another module under
cxgb.
