I suspect TLS implementation is exclusively in the userspace.  That 
might have a distinct license scheme, that I do not know.

The OCB patches to ath10k drivers have license schemes that are 
different.  They would cover generic files deep in the kernel wifi 
structures, and files more specific to a particular manufacturer, like 
Compex, or Atheros, Intel, or similar.  They would be a mixed set of 
licenses both GPL and BSD "no warranty" kinds.

I think Atheros licenses are easier to use by open source developpers.

But I do not know what more precisely in TLS userspace licensing might 
block the use of TLS over 802.11-OCB?

I do know, however, that there are huge obstacles in making PKI for 
vehicular networks like we have PKI for the Internet at large.  There's 
no agreed Certificate Authority for vehicular networks, yet there is 
agreement that the Internet CAs would not be ok for vehicular networks. 
  It is hard to obtain certificates for vehicular networks.

Maybe that difficult situation of CA for vehicular networks relates to a 
potential licensing problem of TLS?
