[M] Change in osmo-bts[master]: Use polling based LAPDm with frame numbers
by jolly 13 Nov '23

13 Nov '23

jolly has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-bts/+/35007?usp=email ) Change subject: Use polling based LAPDm with frame numbers ...................................................................... Use polling based LAPDm with frame numbers Osmo-bts uses the new polling based LAPDm implementation. The OML message NM_ATT_T200 is ignored, because T200 timeouts are set to the minimal response time. Longer timeouts would cause lower throughput in case of lost frames. Shorter timeouts would cause LAPDm to fail.
