RPC/RDMA: check selected memory registration mode at runtime.
At transport creation, check for, and use, any local dma lkey. Then, check that the selected memory registration mode is in fact supported by the RDMA adapter selected for the mount. Fall back to best alternative if not. Signed-off-by: Tom Talpey <talpey@netapp.com> Acked-by: Tom Tucker <tom@opengridcomputing.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
