Description

The following LCLS tests fail:

BSC_Tests_LCLS.TC_lcls_connect_break
BSC_Tests_LCLS.TC_lcls_connect_clear
BSC_Tests_LCLS.TC_lcls_gcr_bway_dont_connect_csc

The tests fail because is for the same for all three tests:
"Received non-matching ASSIGNMENT COMPLETE"

All three tests expect the following ASSIGNMENT COMPLETE:

14:06:55.266136 10 MSC_ConnectionHandler.ttcn:842 {
    discriminator := '0'B,
    spare := '0000000'B,

    lengthIndicator := ?,
    pdu := {
        bssmap := {
            assignmentComplete := {
                messageType := '02'O,
                rR_Cause := *,

                    lCLS_BSS_StatusValue := '0001'B,
                    spare := '0000'B
                }
            }
        }
    }
}

For all three tests, osmo-bsc sends the following message:

                    uDPPortValue := 11002
                },
                speechCodec := {
                    elementIdentifier := '7E'O ("~"),

                    codecElements := {
                        {
                            codecType := GSM_FR (0),
                            tF := '0'B,
                            pT := '0'B,
                            pI := '0'B,
                            fI := '1'B,
                            extendedCodecType := omit,
                            s0_7 := omit,
                            s8_15 := omit
                        }
                    }
                },
                codecList := omit,
                lCLS_BSS_Status := omit
            }
        }
    }
}

We can see that the lCLS_BSS_Status is missing. This is why the testcases fail.

Notw: The problem is also reproduceable using the follwing git state, which
is just before the mgw/mgcp_client changes were merged.
