d4f3003c56 nl80211: Configure Beacon frame TX rate if driver advertises support
If the driver advertises support for setting Beacon frame data rate,
allow the user to configure this rate as part of starting the AP. Only
one Beacon frame TX rate is allowed.

Drivers advertising such support should set corresponding flag via the
NL80211_ATTR_EXT_FEATURES attribute.

660103eca9 nl80211: Use the monitor interface only without device_ap_sme support
The places using drv->use_monitor were already skipping creation of the
monitor interface if drv->device_ap_sme == 0. This means that the
monitor interface operations would not have worked anyway and it is safe
to set drv->use_monitor to zero for all such cases. This fixes an issue
with management frame subscription not happening properly for the case
where the AP SME is in the driver and the driver supports monitor
interfaces (for other purposes).

This commit also removes the check for monitor support and the
previously used workaround that cleared drv->use_monitor in
drv->device_ap_sme == 1 case if monitor interface was not supported
since that condition cannot occur anymore.

cc9985d1b1 Set default scan IEs to the driver (QCA vendor extension)
This makes wpa_supplicant set default scan IEs to the driver (if the
vendor command is supported). The driver can use these IEs in the scan
requests initiated by the driver itself. Also the driver can merge these
IEs into further scan requests that it receives, in case if the scan
request doesn't carry any of the IEs sent in this command.

0e92fb8fae rfkill: Match only the correct expected wiphy rfkill
On systems that have multiple WLAN rfkill instances, the rfkill code
can become confused into thinking that the device was unblocked when
in fact it wasn't, because it only matches on the WLAN type.

Since it then stores the new (unblocked) state from the wrong rfkill
instance, it will never retry the failing IFF_UP operation and the
user has to toggle rfkill again, or otherwise intervene manually, in
this case to get back to operational state.

Fix this by using the existing (but unused) ifname argument when the
rfkill instance is created to match to a specific rfkill index only.

As a P2P Device interface does not have a netdev interface associated
with it, use the name of a sibling interface to initialize the rfkill
context for the P2P Device interface. For nl80211, as the wiphy index
is known only after getting the driver capabilities from the kernel,
move the initialization of the rfkill object to
wpa_driver_nl80211_finish_drv_init().

09ea4309b6 nl80211: Add support for multiple scan plans for scheduled scan
Add 'scan plans' to driver scan parameters for scheduled scan.
Each 'scan plan' specifies the number of iterations to run the scan
request and the interval between iterations. When a scan plan
finishes (i.e., it was run for the specified number of iterations),
the next scan plan is executed. The last scan plan will run
infinitely.

The maximum number of supported scan plans, the maximum number of
iterations for a single scan plan and the maximum scan interval
are advertised by the driver.
