An INTERFACE_DISABLED event received on an interface that is
currently operating a P2P GO means that the group session ended.
In such a case, if the interface was dynamically added remove it, and
if not, remove all the network blocks that are temporary, assuming
that if needed a new session will be started by an external entity.
The use case was triggering rfkill (both SW and HW). This case popped up
as part of a testing cycle, where after a toggle in the rfkill state,
the result was that the interface was not deleted, but on the other hand
the wpa_supplicant did not configure the kernel to re-start the AP
functionality again.

On scan results event if a concurrent P2P scan was triggered previously,
scan results processing is canceled, p2p_find executed, and a new sta
scan is triggered (pending scan). However, this new sta scan does not
restore the scan_req value of the previous scan (whose scan result has
been canceled).
If we are currently connected to an AP and use ap_scan=2, the new
triggered scan will cause an associtation-without-scan in
wpa_supplicant_scan:
(ap_scan == 2 & scan_req != MANUAL_SCAN_REQ)
=> wpa_supplicant_assoc_try()
causing an association error and a disconnection.
This patch fixes this issue by restoring the previous scan_req value.

Relative time shouldn't be calculated based on gettimeofday
because that clock can jump (e.g., when the time is adjusted
by the system administrator.)
On systems where that is available, use CLOCK_BOOTTIME (on
fairly recent Linux systems, this clock takes into account
the time spend suspended) or CLOCK_MONOTONIC (on Linux and
some POSIX systems, this clock is just freely running with
no adjustments.)

The shorter 250 ms wait for the next scan request can be used also for
the case of persistent group re-invocation instead of just formation of
a new group. This speeds up the process and makes this more robust
especially in cases where the GO is using MCC.

Only force_freq was used in the wpas_p2p_set_own_freq_preference() call
which allowed the P2P module channel re-selection to ignore the
preference for using a channel we are already using. Fix this by setting
either force_freq or pref_freq as the preference based on which one is
set. This allows p2p_ignore_shared_freq parameter to be used whether to
prefer the shared frequency in this case.

There is no need to use wpas_p2p_num_unused_channels() here in the
default configuration of p2p_ignore_sahred_freq=0, so re-order the
conditions to skip that operation. This is a bit more efficient and the
debug log is also a bit cleaner in the default case.

p2p_ignore_shared_freq=1 was supposed to allow a MCC-capable device to
ignore a preference for using the same channel on multiple interfaces.
However, it was not used when inviting a peer to re-invoke a persistent
group. This case needs special handling since the peer's channel list is
not available to perform channel reselection and the operating channel
indicated in the Invitation Request frames ends up getting used as the
operating channel if the transmitted of that frames becomes the GO.

Commit 0d08efa447 modified
wpas_p2p_setup_freqs() design to use number of MCC channels capability
from the driver. However, it resulted in regression on how the preferred
vs. forced channel selection is done in the case of a MCC device.
force_freq was set unconditionally even though this was supposed to be
done only if no additional channels are available. pref_freq needs to be
used when possible to avoid preventing connection.

While starting from PNO start context, the scheduled scan was not
setting the flag wpa_s->scanning. This was resulting in the subsequent
SCAN command to proceed further and send command to nl80211/cfg80211.
The expected behavior of cancelling sched_scan was not happening here.
While sched_scan is in progress and a legacy scan comes on the
cli/socket, the sched_scan is cancelled and normal scan is allowed to
continue. However, sometimes sched_scan cancelled event comes a bit
delayed and we will send out the scan command before the wpa_s->scanning
is cleared. Instead, reschedule the incoming scan req if the
wpa_s->scanning shows that it is still in progress.

There are use cases requesting the host driver to initiate the TDLS
setup with the peer only when configured by the external applications.
Thus, enable this control by tdls_external_control=1 and pass the
requisite information for the specific TDLS operation to the driver
on the request from such use cases.
This operation mode expects the driver to initiate TDLS link
automatically based on signal strength and traffic to a peer and tear
down links whenever they are not used or suitable due to signal strength
etc. The list of peers with which such operations are to be performed
are provided with the TDLS driver operations.
