/* 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/)
*
* It has also been used for Tetra by the OsmocomTETRA project.
* (http://tetra.osmocom.org/)
*
* GSMTAP also carries payload in various formats of WiMAX interfaces.
* It uses the wimax plugin to decode the WiMAX bursts.
