This series updates the legacy STATUS indications for VHT/HE
connections.

Patch 1 fixes ieee80211ac=1 so that it is reported only for actual
VHT/IEEE 802.11ac associations instead of being set based only on the
presence of a VHT Capabilities element in the Association Response.

Patch 2 adds a corresponding ieee80211ax=1 STATUS indication for actual
HE/IEEE 802.11ax associations, while excluding EHT associations.

Why would this be done? That feels misleading and an unexpected change
to existing users of that information. An HE STA is also a VHT STA in
the 5 GHz band and an EHT STA is also an HE STA as far as the IEEE
802.11 standard is concerned.

Thanks for pointing this out. I agree that the previous change would be
misleading and could break existing users that interpret ieee80211ac=1
as VHT being part of the association rather than as an exclusive Wi-Fi
generation indication.

I'll respin this so that wifi_generation remains the exclusive
generation indication, while ieee80211ac/ieee80211ax are non-exclusive
STATUS indications based on connection_vht/connection_he.
