This patch adds a new nfs_client_rdma_enable variable to /etc/rc.d/nfsclient to enable the client side of NFS over RDMA. The client side of NFS over RDMA requires the nfsclrdma.ko module, which is still under test/review. I wanted to get the "glue" into main so that others could test the module more easily. Avaliability of the module will be announced on freebsd-current@ soon. It should not affect non-RDMA operation. I've specified a long MFC, since the module still requires extensive testing and, hopefully, a review. MFC after: 3 months
