[Impact]

Within stress reboot tests, iwlwifi may fail to load firmware, triggers retries,
and finally makes wifi operative.

[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.
