Bug description:
[SRU Justification]
[Impact]
Within stress reboot tests, iwlwifi may fail to load firmware, triggers
retries,
and finally makes wifi operative.

(delay=0ms).
[Fix]
Resolved in upstream commit 318c64abfb33 ("iwlwifi: update gl FW for
core80-165
release").
While the iwlwifi firmware updates come with a sequential manner, it pulls a
few
more:
* 765492b8b ("iwlwifi: add new FWs from core81-65 release"), already in Mantic
* a07fd0b96 ("iwlwifi: add new FWs from core83-55 release")
* f27dec616 ("iwlwifi: fix for the new FWs from core83-55 release")
These contain firmware blob for ucore 84/86, and are not used by
kernels < v6.7.
[Test Case]
Use checkbox reboot stress test case to observe iwlwifi dmesg logs:
$ checkbox-cli run com.canonical.certification::stress/reboot
[Where problems could occur]
Opaque firmware update. No known issue found yet after the update.
[Other Info]
This affects series with kernels that load iwlwifi ucode 83 firmware, namely
Noble, Mantic, and for oem-6.5, Jammy.
