I am testing inter-vrf relay.
I am enabling display-filter and seeing that vpn sub-option of 82 is showing
error.
However functionality is working fine.

According to RFC 6607, the Option 82 suboption 151 can either carry the vrf
name which can be of variable length or the vpn id which is exactly 7 bytes.
Our relay agent uses the ascii format when filling the suboptions and the type
is also set as such.


    Option: (82) Agent Information Option
        Length: 32
        Option 82 Suboption: (1) Agent Circuit ID
            Length: 4
            Agent Circuit ID: 1a616000
        Option 82 Suboption: (2) Agent Remote ID
            Length: 6
            Agent Remote ID: 002698193641
        Option 82 Suboption: (151) VRF name/VPN ID
            Length: 4
            [Expert Info (Error/Protocol): Invalid length (expected 7 bytes,
found 4 bytes)]
                [Message: Invalid length (expected 7 bytes, found 4 bytes)]
                [Severity level: Error]
                [Group: Protocol]


This needs to be fixed in the corresponding vpn/vrf dissector.
