When the NFC connection handover message received from a peer indicates
that the peer is operating as a GO on a specific channel, use that
information to avoid having to go through full scan. In addition, skip
the separate join-a-group scan since we already know the operating
channel, GO P2P Device Address, and SSID.

It is more useful to be able to build a single NFC carrier record

external components to decide whether to negotiate which alternative

When start PNO request comes from control interface, wpa_supplicant
should wait until ongoing sched_scan (triggered by wpa_supplicant)
gets cancelled. Issuing cancel sched_scan and start PNO scan
one after another from pno_start() would lead wpa_supplicant to clear
wps->sched_scanning flag while getting sched_scan stopped event
from driver for cancel sched_scan request. In fact, PNO scan will
be in progress in driver and wpa_s->sched_scanning will not be set
in such cases.
In addition to this change, RSSI threshold limit is passed as part of
start sched_scan request. This was previously set only in pno_start(),
but the same parameter should be available for generic sched_scan calls
as well and this can now be reached through the new PNO start sequence.

The new control interface command RADIO_WORK can be used by external

exclusive radio control is needed, e.g., for offchannel operations. If

The new radio work item concept can be used to request time for an
operation that requires exclusive radio control, e.g., a scan. Once the
radio is available, the registered callback function will be called.
radio_work_done() must be called once the exclusive radio operation has
been completed, so that the radio is freed for other operations. The
special case of deinit=1 is used to free the context data during
interface removal. That does not allow the callback function to start
the radio operation, i.e., it needs to free the allocated resources
and return.

If the BSS table within wpa_supplicant is flushed, request the driver to
flush its own scan result table during the next scan. This can avoid
unexpected old BSS entries showing up after BSS_FLUSH or FLUSH command
in cases where the driver may maintain its internal cache of scan
results (e.g., cfg80211 BSS table persists at least for 15 seconds).
In addition to doing this automatically on BSS_FLUSH/FLUSH, a new SCAN
command argument, only_new=1, can be used to request a manual scan
request to do same. Though, it should be noted that this maintains the
BSS table within wpa_supplicant. BSS_FLUSH followed by SCAN command can

Previously, GO considered the group to be fully re-invoked after

the client is expected to connect immediately after the invitation
exchange that ends with status=0 (i.e., either client initiated the
exchange or it responded with success), extend group formation timeout
to cover that period until the first successfully completed data
