While testing MST hotplug events on daisy chain monitors, find out that CLEAR_PAYLOAD_ID_TABLE is not broadcasted and payload id table is not reset. Dig in deeper and find out two parts needed to be fixed. 1. Link_Count_Total & Link_Count_Remaining of Broadcast message are incorrect. Should set lct=1 & lcr=6 2. CLEAR_PAYLOAD_ID_TABLE request message is not set as path broadcast request message. Should fix this.
