( https://gerrit.osmocom.org/c/libosmocore/+/35626?usp=email ) Change subject: gsup: Deprecate field pdp_type in favour of pdp_type_nr and pdp_type_org ...................................................................... gsup: Deprecate field pdp_type in favour of pdp_type_nr and pdp_type_org Having both fields in an uin16_t integer makes it difficult and confusing for users for no good reason. Let's have separate fields for each of them. The new fields are defined so that they are ABI compatible with previous uin16 field.
