</div><pre style="font-family: monospace,monospace; white-space: pre-wrap;">port arfcn range encode support from osmo-bsc<br><br>As part of fixing issue OS#3075, we want to migrate support<br>for encoding system information from osmo-bsc to libosmocore.<br><br>This change ports one of the prerequisites for doing so:<br>osmo-bsc code for range-encoding ARFCNs, including tests.<br><br>An osmo_gsm48_ prefix has been prepended to public symbols in<br>order to avoid clashes with existing symbols in osmo-bsc code.<br><br>Change-Id: Ia220764fba451be5e975ae7c5eefb1a25ac2bf2c<br>Related:
