abis_rsl.c: properly handle a REL_IND from the MS
currently our code flattens out the SAPI communicated by a REL IND from the MS, see e.g. abis_rsl.c:2228:
case RSL_MT_REL_IND: /* BTS informs us of having received DISC from MS */ DEBUGPC(DRLL, "RELEASE INDICATION\n"); msg->lchan->sapis[rllh->link_id & 0x7] = LCHAN_SAPI_UNUSED; <--- overridden with zero rll_indication(msg->lchan, rllh->link_id, BSC_RLLR_IND_REL_IND); rsl_handle_release(msg->lchan);
In order to properly detect whether an lchan is completely released or some SAPIs are still active, this needs fixing and a slew of (ttcn3?) tests to verify that it works.
