Instruct the server to listen on the RDMA transport:
$ echo rdma 2050 > /proc/fs/nfsd/portlist
$ echo rdma 20049 > /proc/fs/nfsd/portlist
- On the client system

Regardless of how the client was built (module or built-in), use this
command to mount the NFS/RDMA server:
$ mount -o rdma,port=2050 <IPoIB-server-name-or-address>:/<export> /mnt
$ mount -o rdma,port=20049 <IPoIB-server-name-or-address>:/<export> /mnt
To verify that the mount is using RDMA, run "cat /proc/mounts" and check
the "proto" field for the given mount.

This option enables an RPC client transport capability that
allows the NFS client to mount servers via an RDMA-enabled
transport.
This option allows the NFS client and server to support
an RDMA-enabled transport.
To compile RPC client RDMA transport support as a module,
choose M here: the module will be called xprtrdma.
