For some reason, osmo-bts-trx attempted to interpret/validate the
contents of the downlink TCH block that it was about to transmit. If
such checks are made, they should clearly be in the common part above
L1SAP, and not in the bts-model specific part.
Also, having the checks in place didn't allow us to send an all-zero
downlink block, as is required for detection of uplink FER in a loopback
testing setup, e.g. with CMU-300.

When we're in loopback testing mode for PDTCH, we must make sure to
avoid adding PTCCH blocks to the queue. Only PDTCH blocks must be
enqueued. For the transmit (downlink) side, we already had the PTCCH
check in place.

l1h is allocated in bts_model_phy_instance_set_defaults() and not in
trx_phy_inst_open(). Hence, trx_phy_inst_close() should not free() it!

If lchan-loopback is enabled, We take the uplink frames as received in
PH-DATA.ind and put them into the dl_tch_queue for that lchan. When we
receive PH-RTS.ind, we dequeue frames from that queue and transmit them
in downlink. If no frame is found in queue, we transmit an empty
(all-zero) frame of 23 bytes (CS-1).

using gettimeofday() is not suitable for the GSM frame timer, as it
relies on the normal 'wall clock' system time, which may be adjusted by
ntp, gps or other means at runtime.
Switching to a different clock source means we cannot use
osmo_timer_list anymore, but timerfd integrates just fine with our
libosmocore select() loop handling.

When the lchan is in loopback mode, we loop back all uplink blocks into
downlink blocks. We do not processs any RTP frames for that lchan
anymore. Rather, we discard those RTP frames to avoid mixing
looped-back samples with those received from remote.

We used to have trx_meas_check_compute() and call that from the
bts-specific code in order to iterate over all timeslots and all lchans
in the timeslots if we have to send measurement reports. This was
executed once per frame, and created unequal CPU load over time, which
in turn might increase different per-ts jitter.
Since 2f028c4e2c in April 2017 we have
lchan_meas_check_compute(), which performs this on a per-lchan basis,
and hence CPU load is distributed over all active timeslots.

osmo-gsm-tester detected a regression due to this commit, when running
osmo-bts-trx. The modems timed out when waiting for them to register with the

In some situations (e.g. when trying to do measurements/testing on the
BTS receiver / uplink) it is useful to have a way to disable the radio
link timeout and keep any channel open until deactivated, irrespective
of whether (valid) data is received or not.
This adds a related feature that can be activated by using an
osmocom-specific value of 0xff for the TS 12.21 Connection Failure
Criterion (9.4.14).

Use systemd template specifier for config name instead of hardcoding
it. This will allow to specify different config file name depending on
the name of the service file.
By default sysmobts-mgr.cfg will be used preserving compatibilty with

lc15bts-mgr.cfg will be used. This gives us necessary flexibility to use
BTS-specific configuration.
