[PATCH wireless] wifi: mac80211: correct FILS status codes

[Ria Thomas]

The FILS status codes are set to 108/109, but the IEEE 802.11-2020
spec defines them as 112/113. Update the enum so it matches the
specification and keeps mac80211 consistent with standard values.

The SHA is correct, but the commit message should be "cfg80211: Add 
support for FILS shared key authentication offload"

Note that the current version is IEEE Std 802.11-2024, and it would be useful
to directly reference Table 9-80.

This issue was pointed out by IEEE in "Errata to IEEE Std 802.11ai-2016." In
addition to this issue, that errata also calls out renumbering the "Category
values" in what was then Table 9-47, now Table 9-81, for FILS from 22 to 26.
But the current enum ieee80211_category does not have an entry for FILS, so
that part of the errata does not need to be applied

But while researching this I see the current category 22 enum is incorrect:
	WLAN_CATEGORY_S1G = 22,

since IEEE Std 802.11-2024, Table 9-81 has:
	22 Unprotected S1G
	23 S1G

So that might also need to be addressed by someone.

Thanks, I've noted that the current revision is 802.11-2024.I cited
802.11-2020 because it’s the first revision that defines these status
codes. I can switch to 802.11-2024 if that’s preferred.

Sure, will review the changes and submit the patch separately as S1G related change.

Didn't really matter here, but generally I guess it would be better.

I did apply this now, but I do wonder if we're better off just removing
unused values? We don't (even pretend to) maintain a full definition of
everything 802.11 in the kernel, and don't need to either?

Thanks for applying.
For context, I’m not using these status codes directly today. The change was
mainly to unblock the enum space for upcoming NDP work. This adjustment was necessary
to remove a dependency blocker in my series.

I’m fine with removing unused values altogether. If you prefer, I can follow up with a
cleanup patch that drops unused codes and adds a brief comment noting the list isn’t
exhaustive and new codes should be added on demand.
