wireshark: ip.access PDCH DEACT ACK and NACK missing support to display IE values
See attached pcap file.
Wireshark can currently parse the ip.access PDCH DEACTIVATION ACK/NACK correctly, and shows IEs type like "Channel Number" or "Cause", but doesn't show its values in the tree.
For "Channel Number", it looks like a TV with len(V) = 1 byte. For Cause, it looks like it's a TLV with L = len(V) = 1.
See matching log message from osmo-bts-trx:
