Fail NFSoRDMA mount for GSS Flavour krb5p
To support krb5p for NFSoRDMA,
1> We do encryption of NFS response header + data buffers and copy encrypted data in single large buffer to send over wire as opaque bytes.
2> For RDMA we send nfs_headers and data seperately, so that we can do rdma_writes for data buffers, so single opaque buffer with header+data is not working.
We can do the fix to copy this opaque buffer in RDMA registered memory and do rdma_send.
But using krb5p has these overheads
1> CPU overhead to do encryption of all data buffers
2> Do buffer copies
Which defeats the purpose of using RDMA transport.
Hence until we have a proper optimised solution we plan to fail the RDMA mount for Krb5p.
