Subject: [PATCH AUTOSEL 5.15 136/188] rtw88: 8822c: update rx settings to prevent potential hw deadlock
Date: Mon, 17 Jan 2022 21:31:00 -0500 [thread overview]
Message-ID: <20220118023152.1948105-136-sashal@kernel.org> (raw)
In-Reply-To: <20220118023152.1948105-1-sashal@kernel.org>
From: Po-Hao Huang <phhuang@realtek.com>
[ Upstream commit c1afb26727d9e507d3e17a9890e7aaf7fc85cd55 ]
These settings enables mac to detect and recover when rx fifo
circuit deadlock occurs. Previous version missed this, so we fix it.
