Update ACS driver offload feature for VHT configuration. In addition,
this allows the chanlist parameter to be used to specify which channels
are included as options for the offloaded ACS case.

If the AP/Authenticator receives an EAPOL-Key msg 2/4 for an association
that negotiated use of PSK and the EAPOL-Key MIC does not match, it is
likely that the station is trying to use incorrect PSK/passphrase.
Report this with "AP-STA-POSSIBLE-PSK-MISMATCH <STA addr>" control
interface event.

Add handling logic for DFS offloaded case, and add a helper function
that takes the frequency (MHz) as a param and returns 1 if given channel
requires DFS, or 0 otherwise.

When DFS offloading capability is supported by the driver, the driver
should use these events to indicate when a radar pattern has been
detected, channel availability check (CAC) has been completed, aborted
or finished after the non-occupancy period is over on a DFS channel.
Also, add a new driver.h event to be used by NL80211 to indicate CAC
Started event on a DFS channel.

SAE authentication fails likely with wrong password. This commit adds a
notification of the failure to the upper application (UI) so that the
application can notify suspection of a wrong password to the user. The
control interface monitor even for this is "MESH-SAE-AUTH-FAILURE

This modifies struct wpa_ptk to allow the length of KCK and KEK to be

The ANQP verification/parsing is done only after the GAS_DONE indication
is sent over the control interface. This means that in case the ANQP
parsing fails there is no indication to the upper layers. Add an
ANQP-QUERY-DONE event that reports the status of the ANQP parsing.

A new "CTRL-EVENT-EAP-PEER-ALT depth=<i> <alt name>" event is now used
to provide information about server certificate chain alternative
subject names for upper layers, e.g., to make it easier to configure
constraints on the server certificate. For example:
CTRL-EVENT-EAP-PEER-ALT depth=0 DNS:server.example.com
Currently, this includes DNS, EMAIL, and URI components from the
certificates. Similar information is priovided to D-Bus Certification
signal in the new altsubject argument which is a string array of these
items.

The new VENDOR_ELEM value 13 can now be used to add a vendor element

This allows vendor specific information element to be used to advertise
support for VHT on 2.4 GHz band. In practice, this is used to enable use
of 256 QAM rates (VHT-MCS 8 and 9) on 2.4 GHz band.
This functionality is disabled by default, but can be enabled with
vendor_vht=1 parameter in hostapd.conf if the driver advertises support
for VHT on either 2.4 or 5 GHz bands.

There should not be a mesh-specific mechanism for setting up channel
parameters since that will just result in duplicated code. IBSS, mesh,
and AP mode can use the same data structures and parameters for setting
up such parameters.
