From 7814a832980caa1206a3f217ef79f1a19831305a Mon Sep 17 00:00:00 2001
From: Neels Hofmeyr <neels@hofmeyr.de>
Date: Wed, 26 Dec 2018 00:40:18 +0100
Subject: [PATCH] use osmo_rat_type from libosmocore

Replace locally defined enum ran_type with libosmocore's new enum
osmo_rat_type, and value_string ran_type_names with osmo_rat_type_names.

The string representations change, which has cosmetic effects on the test suite
expectations.

Depends: I659687aef7a4d67ca372a39fef31dee07aed7631 (libosmocore)
Change-Id: I2c78c265dc99df581e1b00e563d6912c7ffdb36b
