Subject: [PATCH 0/2] Set CLEAR_PAYLOAD_ID_TABLE as broadcast request
Date: Mon, 22 Feb 2021 12:00:25 +0800	[thread overview]
Message-ID: <20210222040027.23505-1-Wayne.Lin@amd.com> (raw)

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.
