commit 8623c372ccd739b073c405bf475be3c3f0aab5e3
Author: Ivan Kluchnikov <kluchnikovi(a)gmail.com>
Date: Wed Aug 23 17:53:37 2017 +0300
transaction: Add new function trans_find_by_lchan
Function returns transaction for given lchan.
In case of active call hold procedure it could be two transactions in a list with
links to the same lchan:
* transaction for call on hold
* transaction for active call.
In this case function ignores transaction which was put on hold and returns active
call transaction.

commit 688915abc7d64bf8e0ce25db96ccf14f98e917f9

handover_decision: Fix condition for power budget handover attempt
Handover attempt for power budget case should be performed every N SACCH frames,
where N = Power Budget Interval.
First measurement report with mr->nr = 0 was used for the first handover attempt
in this case, which is not correct, because first usable report should have
mr->nr = net->handover.pwr_interval-1.
Moreover using the first measurement report with mr->nr = 0 for handover attempt
could lead to unnecessary handover, because usually av_rxlev for first measurement
report
from MS is worse than for following reports.
