Display filters can test the fields in a given packet, but they do not have any mechanism for maintaining state, so they cannot choose to match a packet that has a TLV with some value that some TLV in a *previous* packet that matched the filter has - they can only choose to match a specified (constant) value. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <[email protected]> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:[email protected]?subject=unsubscribe
