52a3257621 6 GHz: Change 6 GHz channels per IEEE P802.11ax/D6.1
The channel numbering/center frequencies was changed in IEEE
P802.11ax/D6.1. The center frequencies of the channels were shifted by
10 MHz. Also, a new operating class 136 was defined with a single
channel 2. Add required support to change the channelization as per IEEE
P802.11ax/D6.1.

2b9713d616 Fill the current opclass in (Re)AssocRequest depending on HT/VHT IEs
The previous implementation was assuming a fixed 20 MHz channel
bandwidth when determining which operating class value to indicate as
the Current Operating Class in the Supported Operating Classes element.
This is not accurate for many HT/VHT cases.

Fix this by determining the current operating class (i.e., the operating
class used for the requested association) based on the HT/VHT operation
elements from scan results.

d0e116f61f Enhance get_mode() to return correct hw_mode with 6 GHz support
The 5 GHz channels are stored in one hw_features set with mode
HOSTAPD_MODE_IEEE80211A while the 6 GHz channels will need to be stored
in a separate hw_features set (but with same mode
HOSTAPD_MODE_IEEE80211A) due to possibility of different HT/VHT/HE
capabilities being available between the 5 GHz and 6 GHz bands.

Iterate through all hw_features sets and check and match the band of
channel supported by the hw_features set while getting the hw_features
set in get_mode(). This allows both the 5 GHz and 6 GHz channels to be
found and correct capabilities to be used in cases where the driver
reports different capability values between 5 and 6 GHz channels.

89450024a8 wpa_supplicant: Pass in operating class for channel validity checks
This is needed to allow the 6 GHz operating classes to be compared
against the driver support channels since the channel numbers are not
really unique identifiers of a channel even within a single band.

464dcfd030 HE: Remove VHT_ prefix from CHANWITDH_* define
The bandwidth values are shared between VHT and HE mode so remove the
VHT specific prefix.

b06d60a902 Use freq_list to constrain supported operating class information
If a station is configured to allow only a subset of frequencies for an
association, the supported operating classes may need to be more limited
than what the hardware supports.

If user has disabled HT or VHT, those related operating classes
should not be advertised as supported.

1ac4dba31a wpa_supplicant: Extend verify_channel() and make it global
Extend verify_channel() to return whether IR is allowed on the channel
or not, and make it a global function so it can be used in other files,
too. This makes this function useful for checking not only if a channel
is supported but also if it is allowed for active and passive scan.

065c029a55 Remove MBO dependency from Supported Operating Classes element
Supported Operating Classes element and its use is define in the IEEE
802.11 standard and can be sent even when MBO is disabled in the build.
As such, move this functionality out from the CONFIG_MBO=y only mbo.c.
