Hi Sinjo, I wonder whether we should be allocating gsmtap types for protocols which had to use alone so far. For instance in GSM I see RLC/MAC, LLC, SNDCP, etc. but those were never really necessary afaik because they always come on top of Um, which is the protocol we encapsulate with gsmtap. I understand that somebody may want to encapsulate eg LLC directly, but until there's a explicit need for it I'd perhaps avoid adding them to the list. AFAIU "uint8_t metadata[0];" is where the T16L16V is placed?
