Allow passing low link quality buffers to upper layers
We want to always call l1if_tch_rx and l1sap_up in order to avoid losing triggering events on the upper layer. With this change, the upper layer will increase correctly seq + ts for RTP. It will then send an RTP packet with only the header and no payload, which is not correct but at least we avoid drifting the RTP clock. Upcoming patch in the series solves this issue. This patch assumes that we are not lossing data events from the physical layer and that we receive an event every 20ms, even if the MS is not transmitting due to DTX. Depends on libosmocore If4ae20c22b881e94585dad710f17b9e37f77bf82 Change-Id: If5df8940fab833eb4e3ed851880b66987d356031
