The AFS bias actually should not apply to local cell lchans, because it
makes no sense for intra-cell considerations:
- same-cell lchans obviously have identical rxlev;
- any nonzero AFS bias thus always raises the TCH/F above the TCH/H;
- for intra-cell reassignment, the power budget hysteresis is,
naturally, not applied.
So, before this patch, setting AFS bias even to only 1 would
unconditionally move all (AMR) TCH/H lchans over to free TCH/F lchans in
the same cell.
Recent patch Id40d1cf8b58410c7d4eb87407fe8b8106e352438 implements
explicit upgrade from TCH/H to TCH/F *if* the TCH/H is experiencing low
rxqual or low rxlev, as a proper replacement for intra-cell AFS bias.
