Arch Linux

Description:

After upgrading to kernel 5.19 (tested both linux and linux-zen), wifi reconnect on resume is broken when using NetworkManager + iwd. When downgrading to 5.18 or linux-lts, auto reconnect starts working again. When switching NetworkManager to use wpa_supplicant auto reconnect starts working on newer kernel again. Manual reconnection works using iwd+new kernel.

Hardware:
* Lenovo Thinkpad T480 with "Intel Corporation Wireless 8265 / 8275 (rev 78)" (according to lspci).
* Access point is a Asus AC-68U running the Asus Merlin Firmware.

I have another laptop, with Atheros wifi and the same NM + iwd setup. It does not suffer from this problem. This appears to
be specific to this hardware.

The following messages show up in dmesg/journalctl when the problem is observed (MAC addresses and SSID changed for privacy):

Additional info:
* package version(s):
- linux-5.19.2.arch1-2
- networkmanager-1.38.4-1
- iwd-1.29-1 (broken)
- wpa_supplicant-2:2.10-5 (works)
* config and/or log files etc.
* link to upstream bug report, if any: I don't know which package is the culprit, so I have not reported this upstream, since I don't know which upstream to report to.

Steps to reproduce:
1. Suspend computer with iwlwifi using NetworkManager + iwd
2. After computer has gone to sleep, wake it up
3. Observe failure to reconnect to wifi network that was connected before.
