Bug description:
[Impact]
In some cases, the wow is not configured and the
NM_SETTING_WIRELESS_WAKE_ON_WLAN_IGNORE is set (for to disable
management of wake-on-LAN in NetworkManager).
The network manager only checks the NM_SETTING_WIRELESS_WAKE_ON_WLAN_NONE
bit.
But, the NM_SETTING_WIRELESS_WAKE_ON_WLAN_IGNORE does not be check.
So, the management of wake-on-LAN still is done by NetworkManager.
The killer 500s Wi-Fi does not want the network-manger to manager the
wake-on-LAN so the NM_SETTING_WIRELESS_WAKE_ON_WLAN_IGNORE is set.
(The driver will manager itself.) When the network-manager managers
the wake-on-LAN, all of the Wi-Fi functions will be lost after the OS
resumed from suspend.
[Test Case]
On a machine with killer 500s Wi-Fi and install the Qualcomm's driver.
Step 1. Enter suspend (s2idle)
Setp 2. Resume from suspend
After resume from suspend, the Wi-Fi function still is normal.
You can download the kernel and linux-firmware that backport the Qucalcomm's
dirver fro focal from below link:

[Regression Potential]
* This patch modifies the wake on lan parameters, please test that
the corresponding feature still works fine with the different
configuration values.
1. Magic packet test:
Set Wake on Wireless to off
Send magic packet to the system
Ensure it does not wake up
Set Wake on Wirless to on
Send magic packet to the system
Ensure it does wake up
2. Wi-Fi function test after resumed from suspend:
After resume from suspend, the Wi-Fi should work normally.
Scan APs.
Connect to an AP.
