The special case of non-zero status code used in a GAS Comeback Response
frame to indicate that additional delay is needed before the response is
available was not working properly. This case needs to allow the status
code check to be bypassed for the comeback case prior to having received
any response data.

PD Response is sent out using a 200 ms offchannel wait, but that wait
was not cancelled on TX status report. This could result in offchannel
operation being left waiting unnecessarily long. Fix this by making the
P2P_NO_PENDING_ACTION case in Action TX callback cancel the wait if a
pending wait is marked (and mark this for PD Response).

It looks like some deployed devices may send an invalid supported
operating class element (length = 0) in TDLS Setup messages. With
cfg80211, this results in the NL80211_CMD_SET_STATION command failing
due to an invalid argument (cfg80211 mandates supported operating
classes information to have a length of 2..253 octets).
Work around this interop issue by ignoring the Supported Operating Class
element if it has invalid length.

If the RADIUS server includes deauthentication request in Access-Accept,
send a WNM-Notification frame to the station after 4-way handshake and
disconnect the station after configurable timeout.
A new control interface command, WNM_DEAUTH_REQ, is added for testing
purposes to allow the notification frame to sent based on local request.
This case does not disconnect the station automatically, i.e., a
separate control interface command would be needed for that.

If the RADIUS server includes the WFA RADIUS VSA in Access-Accept to
indicate need for subscription remediation, copy the server URL from
the message and send it to the station after successfully completed
4-way handshake (i.e., after PTK is set to allow PMF to work) in a
WNM-Notification.
AP must not allow PMKSA caching to be used after subscription
remediation association, so do not add the PMKSA cache entry whenever
the authentication server is indicating need for subscription
remediation. This allows station reassociation to use EAP authentication
to move to non-remediation connection.

Add IPv6 support when using udp/udp-remote control interface using the
following new build configuration options:
CONFIG_CTRL_IFACE=udp6
CONFIG_CTRL_IFACE=udp6-remote
This is useful for testing, while we don't need to assign IPv4 address
(static or using DHCP) and can just use auto configured IPv6 addresses
(link local, which is based on the MAC address). Also add scope id
support for link local case.
For example,
./wpa_cli
./wpa_cli -i ::1,9877
./wpa_cli -i fe80::203:7fff:fe05:69%wlan0,9877

The regulatory rules in Japan do not allow OFDM to be used on channel
14. While this was to some extend assumed to be enforced by drivers
(many of which apparently don't), it is safer to make hostapd enforce
this by disabling any OFDM-related functionality. This tries to avoid
backwards compatibility issues by downgrading the mode rather than
rejecting the invalid configuration.

Add Power Constraint information element to Beacon and Probe Response
frames when hostapd is configured on 5 GHz band and Country information
element is also added. According to IEEE Std 802.11-2012 a STA shall
determine a local maximum transmit power for the current channel based
on information derived from Country and Power Constraint elements.
In order to add Power Constraint element ieee80211d option need to be
enabled and new local_pwr_constraint config option need to be set to
unsigned value in units of decibels. For now this value is statically
configured but the future goal is to implement dynamic TPC algorithm
to control local power constraint.

Suppose we have multiple peers and we have peers advertising SD
capability, but no services registered for advertising. In this case,
even if there are multiple broadcast queries set, we might end up
sending only the lastly added broadcast query to the same device (since
SD_INFO won't get set for the first broadcast query). Add support for
multiple wildcard queries to be tracked to enable this type of use
case.
Some times it is seen that before advancing to next device in the list,
the scan results come and update SD_SCHEDULE flag. This will result in
sending the already sent query to the same device without giving chance
to other devices. This issue again is seen with peer devices advertising
SD capability without any services registered.
