Hi,

Wireshark incorrectly reports a OPEN_DELEGATE_READ in NFSv4 capture as
OPEN_DELEGATE_NONE.

This issue has been observed in 1.10 and and 1.10rc2. 1.8.6 however reports
this correctly.

Attaching shortly the trace details.

Please see the details of the capture:

------------------------
Output from a 1.8.6:

tshark -V -r 80-nfsserver.pcap -R  "frame.number==612"

                    who: <EMPTY>
                        length: 0
                        contents: <EMPTY>

This correctly reports the delegation as a read delegation.

Now the same frame within 1.10:

Network File System, Ops(7): PUTFH SAVEFH OPEN

        Opcode: OPEN (18)
            Status: NFS4_OK (0)

            change_info

                .... .... .... .... .... .... .... ..0. = confirm: Unknown (0)
            Delegation Type: OPEN_DELEGATE_NONE (0)

Over here the delegation is incorrectly reported as OPEN_DELEGATE_NONE

Thanks,
