Intel Killer(R) Wi-Fi 6 AX1650i/AX1650s 160MHz Wireless Network Adapter (201NGW) [8086:34f0] subsystem [1a56:1651] not supported

[You-Sheng Yang]

[SRU Justification]

[Impact]
These cards are currently not recognized correctly and trying to load
non-existent firmware blob iwlwifi-QuQnj-b0-hr-b0-<rev>.ucode, so the
device probing process fails and WiFi is therefore not functional.

[Fix]
Three new patches are required to bring up this device, and one of them,
"handle switching killer Qu B0 NICs to C0", is still under review in
iwlwifi-fixes tree.

One previously SRU'ed patch, "add support for qu c-step devices", was
replaced with the one in the mainline kernel tree due to a mandatory
preprocessor symbol definition introduced in the differences.

[Test Case]
Tested on AX1650s/AX1650i, as well as 9462/9560.

[Regression Risk]
Low. These patches are mostly around adding support to new devices.

This would take backport-iwlwifi version 8039[1] or newer, or iwlwifi-fixes/pending[2] to have full support.

When enabled, it will take "iwlwifi-Qu-c0-hr-b0-*.ucode" instead of currently requested "iwlwifi-QuQnj-b0-hr-b0-*.ucode" as firmware.

[You-Sheng Yang (vicamo)]

We don't have iwlwifi patches backported for Bionic 4.15 generic/oem kernels. Instead, dkms package backport-iwlwifi is recommended.

[Timo Aaltonen (tjaalton)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[You-Sheng Yang (vicamo)]

Mark linux/Disco as WONTFIX. Should use either backport-iwlwifi-dkms from bug 1835858 or oem-osp1 kernel in Disco.

[You-Sheng Yang (vicamo)]

Mark linux/Eoan as INVALID for Eoan generic kernel has had included all the upstream changes since 5.3.0-11.12.
