From 2338145d5b4e27447bb9026c0bb8251a59d7c20d Mon Sep 17 00:00:00 2001 From: Stefan Sperling Date: Thu, 15 Mar 2018 19:38:15 +0100 Subject: use gsm48_decode_lai2() in gsm0808_dec_cell_id_list() This makes gsm0808_dec_cell_id_list() properly decode 3-digit MNCs. Add a test which encodes/decodes a LAI_AND_LAC list with 3-digit MNCs.
