Subject: [PATCH v2 08/11] rtw88: coex: fix BT performance drop during initial/power-on step
Date: Thu, 12 Nov 2020 11:14:27 +0800	[thread overview]
Message-ID: <20201112031430.4846-9-pkshih@realtek.com> (raw)
In-Reply-To: <20201112031430.4846-1-pkshih@realtek.com>

From: Ching-Te Ku <ku920601@realtek.com>

Force set the coexistence to BT high priority during
WLAN initial/power-on step. Since the duration the related setting
may be not ready yet.

The score board is not related to scan when initialing, remove the scan
parameter.
