From c0a1d844e3e7cd65aa0d884b4d4bbf0351c6df33 Mon Sep 17 00:00:00 2001 From: Po-Hao Huang Date: Fri, 17 Dec 2021 09:27:08 +0800 Subject: [PATCH] rtw88: 8822c: update rx settings to prevent potential hw deadlock [ 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.
