Found the netdev wifi workshop page and looked over the slides quickly,
but the notes page is pretty empty ;-)

This came up in discussion with my colleagues today and I would say from
mac80211 perspective there is more to it than just scanning. In short
the 6GHz band is for HE-only operation so for example only HE rates may
be used. As the bitrates are in ieee80211_supported_band having a
separate 6GHz band seems to have a (slight?) advantage.

Arend
