commit 29cd7a84089b4a29748a0c9723f539bc6005ad99
Author: Harald Welte <laforge(a)gnumonks.org>
Date: Sat Mar 10 11:27:43 2018 +0100
sysmobts: Compatibility with older firmware versions
When using a firmware version < 3.6, the call to l1if_mute_rf()
returned an error, which caused an OML CHG ADM STATE NACK.
Let's check if the l1if_mute_rf() call is an un-mute for all
timeslots (which apparently we do always at start-up). If it is, then
acknowledge it even if muting is not supported by earlier firmwares.
I suppose the change causing this problem was introduced in:
commit b26b8fc77692e851469f3e27b9aeaeff233ffd2e

sysmobts: Do a RF mute at initialization when the RC is locked
With the current change applied, we can run the BTS with earlier
firmware versions than 3.6.0 again. Tested with 3.1 and 2.4
