Add support to configure the allowed frequency list for AP operation
using a QCA vendor interface before NL80211_CMD_NEW_BEACON/
NL80211_CMD_START_AP. hostapd generates the allowed frequency list by
intersecting user configured frequency list and all the frequencies
advertised by the driver including disabled channels. If user doesn't
specify allowed frequency list, all the frequencies advertised by the
driver, including disabled channels, will be configured.

In theory, each device that supports WMM (or the IEEE 802.11 QoS for
that matter) is expected to advertise how many replay counters it
supports and the peer device is supposed to use that information to
restrict the total number of different MSDU priorities (AC/UP) that
might be used. In practice, this is not really done in deployed devices
and instead, it is just assumed that everyone supports the eight
different replay counters so that there is no need to restrict which
MSDU priorities can be used.
hostapd implementation of WMM has advertised support for 16 PTKSA replay
counters from the beginning while wpa_supplicant has not had any code
for setting the supported replay counter fields in RSNE, i.e., has left
the value to 0 which implies that only a single replay counter is
supported. While this does not really result in any real issues with
deployed devices, this is not really correct behavior based on the
current IEEE 802.11 standard and the WMM specification.
Update wpa_supplicant to use similar design to the hostapd RSNE
generation by setting the number of supported PTKSA replay counters to
16 whenever WMM is enabled. For now, this is done based on the
association being for HT/VHT/HE/EHT and also based on the AP supporting
WMM since it is much more likely for the local device to support WMM and
eight replay counters (which can be indicated only with the value that
implies support for 16 counters since there is no separate value for 8).

Add new nested netlink attribute, NL80211_ATTR_EMA_RNR_ELEMS, to send
the reduced neighbor report (RNR) elements to the driver when EMA is
enabled. This attribute includes the count of RNR elements and data at
each index. While generating EMA beacons, the driver will include RNR
group at a given index along with MBSSID group. The last element, if
present, has RNR data common for all EMA beacons such as neighbor APs.

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.

Once ACS picks a channel, iface->freq and iface->conf->channel are
updated. So, AP comes up in the last operating channel when 'ENABLED'
after 'DISABLED' though ACS is configured.
But this will fail for 6 GHz APs since configured_fixed_chan_to_freq()
checks if iface->conf->channel is filled or not irrespective of ACS
configuration, and the checks inside configured_fixed_chan_to_freq()
fail the AP setup. Fix this by clearing iface->freq and
iface->conf->channel in AP setup for ACS configuration.

When writing 64-bit attributes into the netlink buffer, senders may
add a padding attribute to allow the payload of the 64-bit attribute
to be 64-bit aligned. For QCA vendor attributes, currently the
attribute QCA_WLAN_VENDOR_ATTR_PAD in enum qca_wlan_vendor_attr is
defined for this purpose.
Unfortunately, when adding attributes to the netlink buffer, all
attributes at a given level of nesting must be defined in the same
enum so that they can be unambiguously parsed. This means that
QCA_WLAN_VENDOR_ATTR_PAD can only be used to pad 64-bit attributes
defined in enum qca_wlan_vendor_attr.
There are many other QCA vendor enums which define 64-bit attributes,
so add a pad attribute to all of them so that the 64-bit attributes
can be unambiguously padded.

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.
