Changing to formal patch series instead of RFC.
In 802.11ax D4.0 a new band has been proposed. This series contains
changes to cfg80211 for supporting this band. With 2GHz and 5GHz there
was no overlap in channel number. However, this new band has channel
numbers with a range from 1 up to 253. The only place I could find an
issue with this is in cfg80211_wext_freq(). Not sure how to deal with
that so it is not part of this series.
The series applies to the master branch of the mac80211-next
repository.

nl80211: add 6GHz band definition to enum nl80211_band

cfg80211: util: add 6GHz channel to freq conversion and vice versa
cfg80211: extend ieee80211_operating_class_to_band() for 6GHz
cfg80211: add 6GHz in code handling array with NUM_NL80211_BANDS
entries
cfg80211: use same IR permissive rules for 6GHz band
cfg80211: ibss: use 11a mandatory rates for 6GHz band operation
cfg80211: apply same mandatory rate flags for 5GHz and 6GHz

Curious how you are populating the wiphy->bands[6 GHz].
If we don't set ht_cap.ht_supported and/or vht_cap.vht_supported then
cfg80211_chandef_usable() fails, but setting those flags on 6 GHz seems
broken.
Hi Jeff,
Good point. Actually, for 6GHz a couple of (v)ht capabilities are still
applicable and exchanged using HE extended capabilities element. My idea
was that these (v)ht capabilities would be reported to user-space same
as for the other bands so that would imply those flags are also set for
6GHz. This may look odd as the statement "6G is HE only" applies, but
still some (v)ht functionality is used in HE. Despite this it may be
good to extend the cfg80211_chandef_usable() for HE in general and cover
the 6G case as well. The intended driver implementation in brcmfmac is
still being worked on so issues might arise.
Regards,
Arend
