[PATCH v5.7] iwlwifi: pcie: handle QuZ configs with killer NICs as well

[PATCH v5.7] iwlwifi: pcie: handle QuZ configs with killer NICs as well

[Luca Coelho]

From: Luca Coelho <luciano.coelho@intel.com>

The killer devices were left out of the checks that convert Qu-B0 to
QuZ configurations.  Add them.

=====================================

It seems there is a merge error in upstream merge commit fafa7424ba7d,
that it confused the meaning in commit db5cce1afc8d and b3bd6416fc77.
How do you think?

Hi Luca,

I have backported this to Ubuntu kernels in my ppa[1], and it doesn't
really fix firmware crash on Killer(R) Wi-Fi 6 AX1650i 160MHz Wireless
Network Adapter (201NGW), REV=0x354 [8086:a0f0] subsystem id [1a56:1651].

[update]

With that cfg/iwl_trans->cfg usage corrected, this patch brings Killer
series back to live. Thank you.

Thanks for reporting, You-Sheng!

What is the crash that you are seeing? The same one during INIT?

Please note that on v5.6 the code is slightly different, so you need to
use cfg instead of iwl_trans->cfg.

Oops, sorry, this was stuck in my outbox.  I see that you have already
made this change and clarified that it solves the issue.

Thanks!
