/* 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/)
