From: Ilan Peer <ilan.peer@xxxxxxxxx>
When a device supports both the 5GHz band and the 6GHz band,
these are reported as two separate modes, both with mode set to
HOSTAPD_MODE_IEEE80211A. However, as these are different modes,
each with its own characteristics, e.g., rates, capabilities etc.,
specifically differentiate between them by adding a flag to indicate
whether the mode describes a 6GHz band capabilities or not.
