Increase scan timeout guard

I would like to request two patches to be backported to the current Fedora 35 kernel. 

There was a iwlwifi issue that would cause firmware resets and cause
performance to significantly degrade to around ~500Kb/s till the
interface was brought down and then up again. Upstream identified the
issue and there are 2 patches that fix the issue by increasing the
scan timeout[1] and in cases where the firmware resets allows it to
recover quicker[2]. The patch to allow for quicker firmware recovery
is present in Linus' tree and present in the 5.16 rc releases while
the patch to prevent the firmware from crashing in the instance is in
net-next for 5.17.

I've been running the two patches, both are very minor changes in my
opinion, on top of the 5.15 Fedora kernel but it would be great to not
have to continue rebuilding the kernel and I know others that would
benefit from the patches being included.

I believe this impacts any Intel WiFi 6 cards but I hit this on the
AX210 in my Framework laptop.

I have attached the two patches to this bug report but they can also be found upstream and they are attached to the upstream bugs.

mac80211: mark TX-during-stop for TX in in_reconfig was already included in stable 5.15.11. As the timeout change patch is indeed in net-next, I have added it to the Fedora-5.15 tree and it will be included in the 5.15.12 release.

Comment 3 Justin M. Forbes 2022-01-04 14:42:47 UTC
Closing this as the 5.15.12 update is now in updates for all Fedora releases, and includes these 2 patches.
