PDCP is not a protocol that can just be passed to the dissector, you need to give it some context (see struct pdcp_lte_info in packet-pdcp-lte.h - there is a link on the wiki page).

The available options are: - use a log file format that has this information and can be read (currently only IxCatapult .out files) - log from your PDCP application code by sending UDP frames whose headers contain the info (again see wiki page) and capture those frames in Wireshark - configure RLC to call it. Until a couple of days ago, it would only call the PDCP dissector for complete SDUs, but now basic re-assembly is supported).
