** Description changed: + [Impact] + Intel Wireless-AC 9560 requires additional driver support as well as new firmware blobs to function. Without them iwlwifi cannot correctly recognize the device on systems with Comet Lake cpu. + + [Fix] + These changes are cherry-picked from either mainline kernel or backport-iwlwifi. Firmware blob iwlwifi-QuZ-a0-jf-b0-*.ucode is also necessary. + + [Test] + Verified on hardware 02f0:4234 with fw rev 48. + + [Regression Potential] + Low. These changes includes only necessary changes to enable Intel Wireless-AC 9560. + + ====== Original Bug Description ====== + Wireless module not detected by the system with the following error messages in the log: 00:14.3 Network controller [0280]: Intel Corporation Device [8086:02f0] - Subsystem: Intel Corporation Device [8086:4030] + Subsystem: Intel Corporation Device [8086:4030] ...
