From 9a98302de19991d51e067b88750585203b2a3ab6 Mon Sep 17 00:00:00 2001 From: Ping-Ke Shih Date: Thu, 28 Jun 2018 10:02:27 +0800 Subject: [PATCH] rtlwifi: rtl8821ae: fix firmware is not ready to run Without this patch, firmware will not run properly on rtl8821ae, and it causes bad user experience. For example, bad connection performance with low rate, higher power consumption, and so on. rtl8821ae uses two kinds of firmwares for normal and WoWlan cases, and each firmware has firmware data buffer and size individually. Original code always overwrite size of normal firmware rtlpriv->rtlhal.fwsize, and this mismatch causes firmware checksum error, then firmware can't start. In this situation, driver gives message "Firmware is not ready to run!".
