Hello Pau Espin Pedrol, Harald Welte, Jenkins Builder, 

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

Change subject: Forward GPRS SUSPEND REQ from DCCH to PCU socket

Forward GPRS SUSPEND REQ from DCCH to PCU socket

As specified in 3GPP TS 03.60 Section 16.2.1 and 44.018 Section 3.4.15,
a Class B MS is sending a "RR GPRS SUSPEND REQ" via a DCCH to the BTS if
it wants to suspend GPRS services.  The BSS is now responsible to
somehow forward this to the SGSN.  As the Gs interface between BSC and
SGSN is both optional and doesn't have any provision to forward this
message, we have to send it over to the PCU so it can use regular BSSGP
signaling to inform the SGSN of the SUSPEND REQUEST.

This patch requires libosmocore Change-Id
I90113044460a6c511ced14f588876c4280d1cac7 for the related definition of
struct gsm48_gprs_susp_req.
