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. -Kip
