/*! \file gsmtap.h
* gsmtap header, pseudo-header in front of the actua GSM payload.
* GSMTAP is a generic header format for GSM protocol captures,
* it uses the IANA-assigned UDP port number 4729 and carries
* payload in various formats of GSM interfaces such as Um MAC
* blocks or Um bursts.
*
* Example programs generating GSMTAP data are airprobe
* (http://airprobe.org/) or OsmocomBB (http://bb.osmocom.org/)
*/
#pragma once
#include <stdint.h>
/* ====== DO NOT MAKE UNAPPROVED MODIFICATIONS HERE ===== */
/* The GSMTAP format definition is maintained in libosmocore,
* specifically the latest version can always be obtained from
* http://cgit.osmocom.org/cgit/libosmocore/tree/include/osmocom/core/gsmtap.h
*
* If you want to introduce new protocol/burst/channel types or extend
* GSMTAP in any way, please contact the GSMTAP maintainer at either the
* public openbsc@lists.osmocom.org mailing list, or privately at
* Harald Welte <laforge@gnumonks.org>.
*
* Your cooperation ensures that all projects will use the same GSMTAP
* definitions and remain compatible with each other.
