e5117da715 [gprs] gb-proxy: We might receive a NS-RESET for a NS-VC that we already know 
In this case, don't blindly allocate a new NS-VC but rather use the NSEI
to lookup the 'struct gprs_nsvc' for it.

6f65696459 logging: Add 'show logging vty' command to display current log config 
As the logging config is getting more and more complex, it is good
if it can be displayed interactively.

WARNING: This needs libosmocore 0.1.6 or later!

6fab236cbb logging: use 'logging level all' instead of 'logging set log level' 
'logging level' can already parse a human-readable level such as
'debug' or 'notice'.  By setting the global mask within the same
command we can also parse it there.

0a4050c63b [gprs] gb_proxy: Send proper BSSGP STATUS msg in error case 
In order to reuse the existing bssgp_tx_* functions without pulling
in the dependencies of gprs_bssgp.c, we have to move those functions
to gprs_bssgp_util.c

Furthermore, we can remove gbprox_nsi and replace it with bssgp_nsi,
and we can do proper processing of BVC-RESET messages coming from
the SGSN on the signalling BVC.  In that case we need to send RESET
messages to all the BSS.

5658a1a766 [gprs] LLC: Echo back the XID parameters that the MS requested 
In order to finish PDP context activation and start the transfer
of SNDCP N-PDUs, we simply confirm to the MS whatever XID parameters
it requests.  This of course has to be implemented with a proper
XID handshake at some other point.

421cba4b08 [gprs] SGSN SM: Provide IPv4 PDP address in PDP CTX ACT ACCEPT 
The message looks now fine (from wireshark point of view).  However,
we cannot simply echo back the QoS parameters, as the meaning in
uplink and downlink connection is not the same.

11d7c105f8 [gprs] pass BSSGP UL-UNITDATA Cell ID up into GMM layer 
BSSGP stores a pointer to the Cell Identifier IE in msgb->cb, which
is later used by the GMM layer to identify the cell that has sent a
given message.

This now also means that the gsm_04_08_gprs.c code is free of any
legacy references to msg->trx or struct gsm_bts.

in openbsc to do the same.

e6afd60779 [gprs] SGSN: Expect all Identifiers to be stored at highest level 
We now expect the highest level (actual SGSN GMM code) to know
all identifiers for every element in the protocol stack, i.e.
TLLI, SAPI, BVCI and NSEI.  The layer-inetrnal state is looked
up based on those identifiers.

The reason for this is to ensure only the highest level state
needs to be persistent, while everything else can be regenerated
dynamically (e.g. in a SGSN restart)
