In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
This option allows the NFS client and server to use RDMA
transports (InfiniBand, iWARP, or RoCE).

To compile this support as a module, choose M. The module
will be called rpcrdma.ko.

If unsure, or you know there is no RDMA capability on your
hardware platform, say N.
