Hi all!

With the current code in the 'gprs' branch, I am able to get the NS (08.16) and
BSSGP (08.18) layers up and running with the nanoBTS.

The NS RESET and TEST procedures are running fine, as well as the BSSGP RESET
and BLOCK procedures.

I now need to work on patching the system information to indicate GPRS support
and add a SI13 message.

Hopefully at that point, it is possible to receive LLC frames that are being
sent by the MS.

Ignoring Mobility Management for now and considering only single-BTS operation
of GPRS, the biggest remaining items are:

* understand LLC better and implement it
* implement SNDCP
* how to interface the actual network  (using pty's with pppd on top)
* make things more dynamic rather than static at compile time

Regards,
	Harald
