What's FTM WLAN? Don't assume that people know all the acronyms.
This included:
> 1) Registered wcn36xx driver to testmode callback from netlink
> 2) Added testmode callback implementation to handle incoming FTM commands
> 3) Added FTM command packet structure
> 4) Added handling for GET_BUILD_RELEASE_NUMBER (msgid=0x32A2)
> 5) Added generic handling for all PTT_MSG packets
I don't remember the english grammar terminology, but in the commit log
use the form "register", "add" instead of "registered", "added".

Unnecessary whitespace after u32.

Adding few empty lines to the function would make it more readable.

Unrelated change.

This looks odd. If wcn36xx does not need START and STOP commands why add
those in the first place?
