If FT over-the-DS case is enforced through the "FT_DS <BSSID>" control
interface command, the PMF capability check during BSS selection is not
used and that could have allowed PMF to be disabled in the over-the-DS
case even if the local network profile mandated use of PMF. Check
against this explicitly to avoid unexpected cases if the APs within the
same mobility domain are not configured consistently.

As a part of P802.11ax amendment, 6 GHz band operation is added.
Since the 6 GHz channel numbers are overlapping with existing 2.4 GHz
and 5 GHz channel numbers, use frequency to identify unique channel
operation instead of channel number. Channel frequency is unique across
bands.
In the existing QCA vendor interface, wherever missing, add frequency
attributes to identify unique channel operation. In addition, add
comments to document some of the previously missed attributes/values.
Note: If both channel and frequency attributes are present in vendor
command/event and
(a) If both the driver and user-space application supports 6 GHz band
then channel related attributes are deprecated and use frequency
attributes.
(b) If either driver or user-space application or both doesn't
support 6 GHz band then use channel attributes.

This replaces the separately implemented ECDH operations with a single
helper function to avoid code duplication. In addition, this introduces
a workaround for strange OpenSSL behavior where the first
EVP_PKEY_derive(NULL) call to learn the size of the output shared secret
returns unexpectedly large buffer (72 octets when expected 32 octets for
group 19). It is not known what is causing this, but such behavior seems
to be showing up every now and then at least when running hwsim test
cases under UML and apparently mainly (only?) in the sigma_dut
controller cases.

IEEE Std 802.11-2016 is not exactly clear on the encoding of the bit
string that is needed for KCK, PMK, and PMKID derivation, but it seems
to make most sense to encode the (commit-scalar + peer-commit-scalar)
mod r part as a bit string by zero padding it from left to the length of
the order (in full octets).
The previous implementation used the length of the prime (in full
octets). This would work for KCK/PMK, but this results in deriving all
zero PMKIDs for the groups where the size of the order is smaller than
the size of the prime. This is the case for groups 22, 23, and 24.
However, those groups have been marked as being unsuitable for use with
SAE, so this fix should not really have a practical impact anymore.
Anyway, better fix it and document this clearly in the implementation
taken into account the unclarity of the standard in this area.

Add a new vendor attribute QCA_WLAN_VENDOR_ATTR_DISCONNECT_IES
to configure disconnect IEs to the driver. Driver shall fill
these IEs in disassoc/deauth frame.
These IEs are expected to be considered only for the next
immediate disconnection (disassoc/deauth frame) originated by
the DUT, irrespective of the entity (user space/driver/firmware)
triggering the disconnection.
The host drivers are not expected to use the IEs set through
this interface for further disconnections after the first immediate
disconnection initiated post the configuration.
If the IEs are also updated through cfg80211 interface (after the
enhancement to cfg80211_disconnect), host driver is expected to
take the union of IEs from both of these interfaces and send in
further disassoc/deauth frames.

The bootstrapping URI format for DPP was extended during protocol design
to allow a list of channels without having to repeat the same operating
class information for each channel. That change was not included in the
initial implementation of the parser and a channel-list like
"C:81/1,6,11" would not be understood correctly (i.e., only the longer
"C:81/1,81/6,81/11" form would have been parsed correctly).
Fix this by extending the parser to accept both the shorter and longer
form for a list of channels within a single operating class.

Add a QCA vendor sub command QCA_NL80211_VENDOR_SUBCMD_BEACON_REPORTING
to implement beacon reporting feature. Different operations required to
implement this feature can be specified in
QCA_WLAN_VENDOR_ATTR_BEACON_REPORTING_OP_TYPE.
Userspace requests the driver/firmware to periodically report received
Beacon frames whose BSSID matches the current connected BSS's MAC
address. If userspace requests the driver/firmware to send beacon
reports actively, the driver encapsulates the details of the beacon in
an event and sends it to userspace asynchronously. Otherwise, the driver
will only update the beacon in cfg80211 scan cache but will not send any
event to userspace.
If this command is not issued, the current behavior of the
driver/firmware is to update the cfg80211 scan cache only when there is
a scan issued by the host in progress or whenever there is a change in
IEs of the Beacon frames from the current connected BSS.
The userspace requests the driver/firmware to stop reporting beacons
when reporting is not required anymore. If the driver/firmware is not
able to receive Beacon frames because of other Wi-Fi operations such as
off-channel activities, etc., the driver/firmware sends a pause event to
userspace and stops reporting Beacon frames. The driver/firmware
indicates whether the beacon reporting automatically resumes later by
using the QCA_WLAN_VENDOR_ATTR_BEACON_REPORTING_AUTO_RESUMES flag. If
userspace doesn't want the beacon reporting to be resumed automatically,
userspace can send QCA_WLAN_VENDOR_BEACON_REPORTING_OP_STOP command to
the driver to stop beacon reporting.
