This patch proposes extension to GSMTAP to support LTE frames - the same way it
supports UMTS. I've tried to pick defines to be compatible with wireshark.
Suggestions and extensions are highly appreciated.

Hi Max,
@ttsou, you're pretty familiar with LTE right ? Can you give it a
quick look just to get a second opinion. (mine is pretty useless as my
lte knowledge is near zero).

The '-' is an unecessary whitespace change.

1) I'd add a new separate section witht ehe " ==== ..." marker before
/ after and put it after the UMTS section to keep the order. Also add
the same comment that those are for the GSMTAP_TYPE_LTE_RRC (look at
the UM / TETRA / GMR section).
2) tab vs space for alignement of the values
Cheers,
Sylvain

The SCH is a transport channel upon which the other control channels
are mapped. Downlink or uplink SCH won't interact with RRC directly,
so it seems the logical traffic channels DTCH (Dedicated Traffic
Channel) and MTCH (Multicast Traffic Channel) are more appropriate
here.

Thanks for your comments: incorporated @ttsou suggestion on SCH, fixed tab-vs-space.
As for whitespace change in the beginning - I think it's necessary to match usage of
====== header throughout the rest of the file.

I'll give it a couple of days to make sure everybody interested has a
chance to view it, but if there are no other comments / suggestions in
the mean time, I'll push that to master.

Applied.
BTW, you might want to include a signed-off-by line next time.

Thanks.
Is there some git option for that or it's just plain text in a long comment?

Yourself.
The Signed-off-by chain is essentially taking responsibility for the patch.
When taking a patch off the list, I'll add my own line to it to
basically say I looked over the patch, tested it and that to the best
of my knowledge the patch complies with the license.
Cheers,
Sylvain
