The max transmit power of Standard Power (SP) Access Points (AP) on
6 GHz band and APs on 2.4 GHz and 5 GHz bands is limited by effective
isotropic radiated power (EIRP), while the max transmit power of Low
Power Indoor (LPI) APs on 6 GHz Band is limited by power spectral
density (PSD). Therefore the max transmit power of LPI APs grows as the
channel width increases, similar to the noise power which has constant
PSD.
Adjust the SNR of BSSes based on the transmit power config and max
channel width. EIRP limited APs usually have constant max transmit power
on different channel widths, their SNR decreases on larger channel width
because the noise power is higher, while PSD limited APs have constant
SNR over all channel widths.

As per IEEE Std 802.11ax-2021, 11.1.3.8.3 Discovery of
a nontransmitted BSSID profile, an EMA AP that transmits a Beacon
frame carrying a partial list of nontransmitted BSSID profiles
should include in the frame a Reduced Neighbor Report element
carrying information for at least the nontransmitted BSSIDs that
are not present in the Multiple BSSID element carried in that frame.
Add this support by splitting the reduced neighbor report (RNR) in as
many elements as the number of multiple BSSID elements. Each RNR element
excludes the non-transmitting profiles already included in the MBSSID
element at the same index. If present, the last additional group will
have the data common for all EMA beacons such as neighbor AP information
gathered through neighbor reports.
The hwsim test case he_ap_ema demonstrates this support.

The flags that indicate that a channel is allowed for 80/160 MHz use
are divided according to the position of the control channel (e.g.,
HOSTAPD_CHAN_VHT_10_70, HOSTAPD_CHAN_VHT_30_50, etc.).
However, the position of the control channel does not add any extra
regulatory information because when trying to use a 80/160 MHz channel
all the desired bandwidth has to be allowed for 80/160 MHz use,
regardless of the control channel position.
In addition, these flags are set only if the driver reports one
regulatory rule that allows the entire 80/160 MHz bandwidth.
However, even when a 80/160 MHz channel is allowed, in some cases the
bandwidth will be split into several regulatory rules because
different segments of the bandwidth differ in other flags (that don't
affect the use of the bandwidth for VHT channels). So, in such cases
these flags will not be set, although VHT channels are allowed.
As the result, VHT channels will not be used although they are allowed
by the regulatory domain.
Fix this by introducing new flags that indicate if a 2 0MHz channel is
allowed to be used as a part of a wider (80/160 MHz) channel.
The new flags are set for each 20 MHz channel independently and thus
will be set even if the regulatory rules for the bandwidth are split.
A 80/160 MHz channel is allowed if all its 20 MHz sub-channels are
allowed for 80/160 MHz usage.

Enable MLO for SAE authentication when the driver indicates the AP MLD
address in an external authentication request. The MAC address of the
interface on which the external authentication request received will be
used as the own MLD address.
This commit does below for enabling MLO during external SAE
authentication:
- Use MLD addresses for SAE authentication.
- Add Basic Multi-Link element with the own MLD address in SAE
Authentication frames.
- Send SAE Authentication frames with the source address as the own MLD
address, destination address and BSSID as the AP MLD address to the
driver.
- Validate the MLD address indicated by the AP in SAE Authentication
frames against the AP MLD address indicated in external authentication
request.
- Store the PMKSA with the AP MLD address after completing SAE
authentication.
