Re: [PATCH 3/4] gprs: Don't discard SUSPEND/RESUME in bssgp_rcvmsg (TODO)

Currently sending SUSPEND/RESUME messages to this function (like it is done in the osmo-sgsn) results in STATUS messages complaining about an unknown BVCI. The reason is, that these messages rely on a TLLI/RAI pair to identify the context and do not contain an explicit BVCI. This patch modifies bssgp_rcvmsg() to only complain about and unknown BVCI if one is given but a matching context is not found (except for RESET messages). The ctx argument is removed from the functions handling SUSPEND and RESUME since it will always be NULL then. TODO: - test cases - end-to-end test Sponsored-by: On-Waves ehf
