Fix for the HE Channel Center Freq Seg0/Seg1 within the HE 6GHz
Operation Information field. As downgrade of bandwidths for VHT and HE
when using puncturing is TODO for 320 MHz and/or if puncturing is
disabled and bandwidth is 320 MHz, the same rules as for 160 MHz should
be applied for Channel Center Freq Seg0/Seg1 within 6 GHz Operation
Information field.

Legacy modes (VHT, HE) should advertise downgraded bandwidth if
RU puncturing is enabled in EHT mode. This is required for the legacy
stations which cannot parse the EHT Operation elements hence do not
support EHT RU puncturing.

Set TWT responder configurator in the driver parameters only when the AP
is configured with HE enabled. This was already done for the extended
capability bit generation in commit 8de0ff0fa1 ("HE: Add TWT responder
extended capabilities field"), but this parameter for the driver command
to start the AP in _ieee802_11_set_beacon() missed the condition.
Move the ieee80211ax check into the common helper function to cover both
cases. In addition, add a check for disable_11ax to cover the case where
HE is disabled for a specific BSS.

This information element is similar to the CSA one. It contains a
counter and the target color. Once the counter expired, the change to
the new color happens.
Just note the current implementation is based on CCA counter attributes
that only take Beacon and Probe Response framesinto account.
(Re)Association Response frames do not currently have kernel APIs to
decrement the CCA counter since mediatek mcu firmware does not support
it yet and it will be added in future firmware release.

In the 6 GHz Operation Information field, the Channel Center Frequency
Segment 0 field indicates the channel center frequency index for
the 20 MHz, 40 MHz, 80 MHz, or 80+80 MHz channel on which the
BSS operates in the 6 GHz band. If the BSS channel width is 160 MHz
then the Channel Center Frequency Segment 0 field indicates the
channel center frequency index of the primary 80 MHz.
The Channel Center Frequency Segment 1 field indicates the channel
center frequency index of the 160 MHz channel on which the BSS operates
in the 6 GHz band or the channel center frequency of the secondary 80
MHz for the 80+80 MHz channel.

When WMM is disabled, HT/VHT/HE capabilities should not be used for any
STA. If any STA advertises these capabilities, hostapd AP disables HT
capabilities in STA flags during STA assoc, but VHT/HE was not handled
similarly. This could allow a STA to associate in VHT/HE mode even in
WMM disable case.
To avoid this, disable VHT/HE capabilities similarly to HT during STA
association, if WMM is not enabled by the STA.

mode->he_capab is an array and as such, there is no point in checking
whether it is NULL since that cannot be the case. Check for the
he_supported flag instead. In addition, convert the TWT responder
capability bit into a fixed value 1 to avoid any surprising to the
callers. In practice, neither of these changes results in different

The HE Operation field for BSS color consists of a disabled, a partial,
and 6 color bits. The original commit adding support for BSS color
considered this to be a u8. This commit changes this to the actual
bits/values.
This adds an explicit config parameter for the partial bit. The disabled
is set to 0 implicitly if a bss_color is defined.
Interoperability testing showed that stations will require a BSS color
to be set even if the feature is disabled. Hence the default color is 1
when none is defined inside the config file.

The Channel Width field value is 0 for 20 MHz, 1 for 40 MHz, 2 for 80

was not addressed previously correctly since it cannot be derived from
seg0 only.
The Channel Center Frequency Segment 0 field value is the index of
channel center frequency for 20 MHz, 40 MHz, and 80 MHz channels. The
value is the center frequency index of the primary 80 MHz segment for
160 MHz and 80+80 MHz channels.
The Channel Center Frequency Segment 1 field value is zero for 20 MHz,

center frequency for 160 MHz channel and the center frequency index of
the secondary 80 MHz segment for 80+80 MHz channels.

capabilities.
The he_capabilities are now duplicated to store all information for
IEEE80211_MODE_* which hostap cares about. The nl80211 driver fills in
this information when the iftype supports HE. The rest of the code still
only uses the IEEE80211_HE_AP portion but can be extended later to also
use other HE capabilities.
