From 1c95d78f087c9cd78caf17181525c8853d78bf1c Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Wed, 22 Sep 2021 17:56:30 +0200 Subject: [PATCH] ipq-wifi: Work around Plasma Cloud PA1200 5GHz crash It was noticed [1] that the ath10k firmware crashes on 5GHz since OpenWrt 21.02.0. The problem seems to be triggered by the the nonLinearTxFir field in the 5GHz BDF. If baseEepHeader.nonLinearTxFir (offset 0xc2) is 1 then the firmware just crashes when setting up the 5Ghz radio using `ifconfig wlan1 up`: ath10k_ahb a800000.wifi: firmware crashed!
