> What is the purpose of these flags? And why only one bit?
the flag determines whether a given measurement is part of the "RXLEV/RXQUAL-SUB", and not just -FULL.  The SUB are contained of all SACCH blocks in uplink, plus some other blocks. Which blocks depends on the codec.  FR/EFR/HR have some static block numbers (IIRC) while in AMR it's actually dynamically decided whcih block is part of SUB and which not.

Indeed it's unclear why this is part of libosmocore. Maybe jolly wanted to also use it in other software outside of osmo-bts?  In any case I'm not aware of such software. Maybe ask him directly, or on the mailing list.

In any case, I think it's not a good idea to merge changes here if you don't fully understand what they do, sorry.
