Revert "bts: extend bts_chan_load to allow counting tch only"
This reverts commit 308cb0719dca3ba8eed1eff2a2124d44f34d9a28.
Problems in this commit:
openbsc/src/libbsc/chan_alloc.c:523: case GSM_PCHAN_TCH_F_PDCH:
This is actually wrong, GSM_PCHAN_TCH_F_PDCH use ts->flags, not ts->dyn below
(due to historical reasons and could be unified).
560: if (only_count_tch && !chan_is_tch(ts))
This has exactly one effect: it excludes GSM_PCHAN_TCH_F_PDCH when in PDCH
mode, because for all other PDCH (plain PDCH and TCH/F_TCH/H_PDCH in PDCH mode)
below ts_subslots() returns 0 and skips the for() loop. I consider this a bug
in TCH/F_PDCH, to be fixed in an upcoming commit.
I don't see why we need the only_count_tch argument, because this should
normally only count TCH, weren't it for the TCH/F_PDCH bug.
If dyn TS should be counted differently, we should do this in a different way.
