/**
 * @brief Packet types supported by PCAP
 *
 * These codes end up in the pcap file header.
 * If you decide to build a wireshark dissector,
 * you'll need to know that these codes are mapped
 * through the pcap_to_wtap_map[] array in .../wiretap/pcap-common.c.
 *
 * For example:
 *
 *   { 160,		WTAP_ENCAP_USER13 },
 *
 * A file with (vpp) packet type PCAP_PACKET_TYPE_user13
 * aka 160, will need a top-level dissector registered to
 * deal with WTAP_ENCAP_USER13 [=58].
 *
 * Something like so:
 *
 * dissector_add_uint("wtap_encap", WTAP_ENCAP_USER13, vpp_dissector_handle);
 *
 * null 0
 * ethernet 1
 * ppp 9
 * ip 12
 * hdlc 104
 * user0 147 ... user15 162
