In order to retransmit faster in AP mode, hostapd can handle TX status
notifications. When using nl80211, this is currently only possible with
socket control messages. Add support for receiving such events directly
over nl80211 and detecting, if this feature is supported.
This finally allows for a clean separation between management/control
path (over nl80211) and in-kernel data path.
A follow up commit enables the feature in AP mode.
Control port TX status contains the original frame content for matching
with the current hostapd code. Furthermore, a cookie is included, which
allows for matching against outstanding cookies in the future. This
commit only prints the cookie value for debugging purposes on TX status
receive.

That's because wpa_supplicant computed the PMKID using the wrong (old)
MAC address used during the scan. wpa_supplicant updates own_addr when
the interface goes up, as the MAC can only change while the interface
is down. However, drivers don't report all interface state changes:
for example the nl80211 driver may ignore a down-up cycle if the down
message is processed later, when the interface is already up. In such
cases, wpa_supplicant (and in particular, the EAP state machine) would
continue to use the old MAC.
Add a new driver event that notifies of MAC address changes while the
interface is active.

This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.
This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.
Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

This adds a QCA vendor specific nl80211 event to allow the driver to
indicate a list of frequency ranges that should be avoided due to
interference or possible known co-existance constraints. Such
frequencies are marked as not allowed for P2P use to force groups to be
formed on different channels.
If a P2P GO is operating on a channel that the driver recommended not to
use, a notification about this is sent on the control interface and
upper layer code may decide to tear down the group and optionally
restart it on another channel. As a TODO item, this could also be changed
to use CSA to avoid removing the group.

The option of handling upper layer P2P management operations within the
driver/firmware was originally planned to be used with wpa_supplicant,
but this has not really happened and there is no clear sign of this
being needed in the near term either. This functionality has not been
completed and it is certainly not being kept up-to-date or tested. As
such, it is best to remove it for now and if this or something similar
is needed in the future, it can be brought back once a clear need for it
has been demonstrated first.

This driver event was used separately for some Action frames, but all
the driver wrappers converted to this from information that would have
been enough to indicate an EVENT_RX_MGMT event. In addition, the
received event was then converted back to a full IEEE 802.11 management
frame for processing in most cases. This is unnecessary complexity, so
get rid of the extra path and use EVENT_RX_MGMT for Action frames as
well as other management frame subtypes.
