It only include PDCP signalling message (Uplink and Downlink)

Raw data feed to ws_dissector:

  [Protocol ID] [Message Length] [un-ciphered buffer_log]
  For PDCP downlink signalling message, the protocol id is 300
  For PDCP uplink signalling message, the protocol id is 301

Payload feed to packet_pdcp_lte:
