Hi,
RDMA support is available.
We will release an updated driver with RDMA and RoCE support (RDMA over Ethernet) in 3 weeks (and commit it to upstream soon).
The inbox ipoib module is pretty old and has many issues. We will probably update it in the future.
Regards,
Oded Shanoon

Last time I tested FreeBSD 10.0, the basic IB stack was working well (Mellanox HCAs only), but IPOIB support was not usable. Hence, throughput was limited to well below the hardware transfer speed for NFS or any other TCP/IP based protocol. Mellanox developers have been working on it, but I haven't checked the status lately. You might find something in recent FreeBSD kernel commit logs.
Cheers,
JB
