Max gerrit-no-reply at lists.osmocom.orgHello Neels Hofmeyr, Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/4160
to look at the new patch set (#2).
SI2q: fix generation for multiple UARFCNs
* fix insert routine to keep the list sorted by UARFCN
* fix rest octets generator to properly account for offset
* adjust test results accordingly
