# To use the dissector, edit the preferences for DLT_USER to
# add an entry with DLT=147, Payload Protocol=mac-lte-framed.
# For more information see: https://wiki.wireshark.org/MAC-LTE
#
# Please note that this setting will by default only capture MAC
# frames on dedicated channels, and not SIB.  You have to build with
# WRITE_SIB_PCAP enabled in enb/src/stack/mac/mac.cc if you want
# SIB to be part of the MAC pcap file.
