( https://gerrit.osmocom.org/c/osmo-sgsn/+/34120 ) Change subject: sgsn_rim: get rid of MME check in sgsn_rim_rx_from_gtp: ...................................................................... sgsn_rim: get rid of MME check in sgsn_rim_rx_from_gtp: There is no point in checking the MME any further. When the message has reached this code path it is about to be forwarded to BSSGP, so the MME does not play a role in the following code pathes.
