[M] Change in osmo-sgsn[master]: routing area: introduce ran_type on the RA

by lynxis lazus

lynxis lazus has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-sgsn/+/40688?usp=email ) Change subject: routing area: introduce ran_type on the RA ...................................................................... routing area: introduce ran_type on the RA A Routing Area should be unique identified by the RAI. Following this, it is forbidden to have a RAI which is valid in both, GERAN and UTRAN.
