From 604086babc0761512ff7c71e942a4f647d7de6f7 Mon Sep 17 00:00:00 2001 From: Eric Huang Date: Wed, 5 Oct 2022 16:32:08 +0800 Subject: [PATCH 341/389] wifi: rtw89: parse PHY status only when PPDU is to_self Without this fix, some non-self packets are used to count CFO (center frequency offset), and average CFO has unstable variation. Then, it causes unexpected performance.
