Vadim Yanitskiy 12b3921a4a osmo-bts-trx: rx_{tchf,tchh}_fn(): get TDMA FN from meas history ... Once we have an Uplink speech or FACCH frame decoded, we need to hand it over to the upper layers indicating TDMA frame number of the *first* burst corresponding to the beginning of a block. Currently we use libosmogsm's gsm0502_fn_remap() API to calculate the first TDMA frame number from the given last frame number. This API involves iterating over the pre-calculated offset tables for different channel and payload types, and thus imposes some additional CPU cycles. Another downside of the current approach is that we have to perform such lookups several times for each decoded L2 frame, e.g. for FACCH on TCH/AHS we do it three times! In this patch I propose an alternative approach of storing TDMA frame numbers in the measurement history, together with the associated samples. This way we can easily get N-th frame number from there without performing any additional computations, other than what we already do during the measurement processing.
