As in the reply to Pablo, I did it for no particular reason other than
idle curiosity, and given the attempted move to Open 5G I thought
adding MAC support might be useful somewhere along the line.

I think it would not be the best idea to merge SELinux support patches for the
GTP kernel driver without thoroughly understanding the use case, and/or having
some actual userspace implementations that make use of them.  In the end, we may
be introducing code that nobody uses, and which only turns out to be insufficient
for what later actual users may want.

So like Pablo suggested, it would probably be best to focus on
submitting / merging features for things that are either well-defined (e.g.
specified in a standerd), and/or have existing userspace implementations.

Having a solid use case or two is also helpful for those of us who
don't have a GTP/GPRS background.  I did spend some time reading a few
things on GTP, but I don't feel like I've made much of a dent on
understanding how it is actually used.

Harald, Pablo - I know you both suggested taking a slow iterative
approach to merging functionality, perhaps you could also help those
of us on the SELinux side better understand some of the common GTP use
cases?
