+ * GSCON FSM. By then, the GSCON FSM has already changed to the state
+ * ST_WAIT_MDCX_BTS_HO (see gscon_fsm_wait_mdcx_bts_ho()) and waits for
+ * GSCON_EV_MGW_MDCX_RESP_BTS. The signal GSCON_EV_MGW_MDCX_RESP_BTS

+ * MGW negotiation to the GSCON FSM. All we need to do is to dispatch
+ * parent_evt back to the GSCON FSM in order to make it think that the
+ * MGW negotiation is done.
+ *
+ * Unfortunately, there is a problem with this test implementation.
+ * in order to simplfy the test we do not allocate any MGCP Client
+ * FSM but the GSCON FSM will call this function with the fi pointer
+ * pointing to the MGCP Client FSM. This means we get a nullpointer
+ * here and there is no way to distinguish which GSCON FSM called
+ * the function at all (normally we would know through the parent
+ * pointer).
+ *
+ * To get around this problem we populate the fi pointer with the
+ * reference to the GSCON FSM itsself, so we can know who called the
