From 783047e86ec64677f3894bd22576315eee631275 Mon Sep 17 00:00:00 2001 From: Philipp Maier Date: Wed, 29 Mar 2017 11:35:50 +0200 Subject: gsm0808: Add utils for Cell Identifier List The planned support for true A over IP requires the encoding of the a Cell Identifier List element (see also BSS_MAP_MSG_PAGING). This commt adds encoding/decoding functionality and tests for the element mentioned above, however, it is not yet actively used.
