Neels Hofmeyr gerrit-no-reply at lists.osmocom.orgReview at https://gerrit.osmocom.org/7225 bsc: TC_chan_rel_rll_rel_ind: expect full MSC Clear Request This test sends a REL IND from the MS and immediately expects an lchan release. Instead, osmo-bsc patch I0f8c9c4e6b6850b15c70250fd3f88bdf75f9accf decides to signal full BSSMAP Clear Request to the MSC first, so expect that first. Note that this test currently fails, and said osmo-bsc.git patch will make this test pass.
