commit 06dbfbc74388a2e9a7228f4215b884a3139ece56 Author: Gregory Greenman <gregory.green...@intel.com> Date: Wed Oct 26 12:15:12 2022 +0300 iwlwifi: add new FWs from core69-81 release Add the -69.ucode firmwares for the currently supported hardware. This is not the latest core, but we didn't send it before and it still can be useful. I'll check tomorrow whether it will cure the errors I'm getting with kernel 5.19.11-1~bpo11+1 on an AX211 with -71.ucode (regression from 5.18.16-1~bpo11+1 which works on the same hardware/firmware combo).
