From 2422c2158fb51b7ba94e0a8b4ac280c88e0c73a6 Mon Sep 17 00:00:00 2001 From: Ching-Te Ku Date: Thu, 29 Feb 2024 15:45:14 +0800 Subject: [PATCH] wifi: rtw89: coex: Add coexistence policy to decrease WiFi packet CRC-ERR The 2 Bluetooth profiles (Hands free profile & Human interface device) have high duty transmission, it will affect the traffic of WiFi packet frequently. And once the WiFi traffic down to B/G mode, it will need a better success rate to recover the transmission rate. Add new policy option to solve the above situation.
