Hello All,

I have a question regarding GSMTAP , If it is used for sending messages to wireshark only or it has some other significant, like communication between L2 and L3 or communication with layer1, as the uint8_t and uint16_t were widely used in source code

GSMTAP is a purely 'artificial' data format that is used by OpenBTS, airprobe and OsmocomBB to forward GSM MAC blocks (layer 2 frames with 23 bytes length) of the Um interface into wireshark.

There's no other purpuse to it.
