To compile RPC client RDMA transport support as a module, choose M here: the module will be called xprtrdma.

Secure RPC calls with Kerberos require an auxiliary user-space daemon which may be found in the Linux nfs-utils package available from http://linux-nfs.org/. In addition, user-space Kerberos support should be installed. If unsure, say Y.
