Hi all; A check in request please. Some minor updates to the IPDC dissector. Fixing missing handling for tags 0x6F and 0x70 (send and receive encoding type). Shorten fields displayed in COL_INFO. Display information about all IPDC packets in COL_INFO if there's more than one. Thanks, -- Josh Bailey (joshbailey@xxxxxxxxxx)
