+ * rate_ctr API uses several osmocom select loop features, and as a result,
+ * calls to it must be done through the main thread (the one running the osmocom
+ * loop in osmo-trx).
+ * Since read/write from/to SDR is done in separate threads (even read and write
+ * each use a different thread), we must use some sort of message passing system
+ * between main thread feeding rate_ctr structures and the Rx/Tx threads
+ * generating the events.
+ * The idea is that upon read/write issues, lower layers (SDR APIs) provide us with
+ * underrun/overrun/droppedPackets information, and in that case we pass that up
+ * the stack through signal <SS_DEVICE,S_DEVICE_COUNTER_CHANGE> with signal_cb
+ * being a pointer to a "struct device_counters" structure, which contains
+ * device (implementation agnostic) statful counters for different kind of
+ * statistics.
+ * That signal is processed here in device_sig_cb, where a copy of the "struct
+ * device_counters" structure is held and the main thread is instructed through
+ * a timerfd to update rate_ctr APIs against this copy. All this is done inside
+ * a mutex to avoid different race conditons (between Rx andTx threads, and
+ * between Rx/Tx and main thread). For the same reason, callers of signal
+ * <SS_DEVICE,S_DEVICE_COUNTER_CHANGE> (device_sig_cb), that is Rx/Tx threads,
+ * must do so with PTHREAD_CANCEL_DISABLE, in order to avoid possible deadlocks
+ * in case the main thread decides to cancel other threads due to a shutdown
+ * operation (fi SIGKILL received)
