The RPC-over-RDMA dissector doesn't work unless the ConnectRequest exchange
appears in the capture. If a capture is an excerpt of some traffic without the
CREQ, the RPC-over-RDMA dissector ignores the traffic completely.

Often NFS captures are done while a problem is ongoing on one or more
connections. There is way too much traffic involved to capture from beginning
to end.
