The recent unified scan api change introduced issues
when stopping ongoing scans, since both regular and
sched scan now use same stopped notification.
When issuing a new scan right after a running one,
we get the "old" notification and handle it wrongly
as notification for the current scan.
Fix it by introducing a new function that make sure
we consume the pending notifications before issuing
a new scan.

According to new requirements, the ACK / CTS kill mask is
not related to reduced TX power anymore. This allows to
remove the code that tracked reduced TX power enablement
across different interfaces.
The ACK / CTS kill mask is now fetch from a table. It
depends on the Activity grading (activity from BT) and on
the Look Up Table (LUT) type.

The Remain On Channel framework added to the firmare is
a bit like time events. It allows the driver to request
the firmware to be on a certain channel for a certain time.
Unlike the time events, the ROC infrastructure doesn't need
a MAC context in the firmware - it uses a generic context
called "auxiliary framework".
This is useful for any offchannel activity that is not bound
to a specific MAC.
The flow is synchronized much like with time events:
1) The driver receives an action frame from the wpa_supplicant
via nl80211 that requests to be sent offchannel.
2) The driver sends an Aux ROC command (0x53) to the firmware.
3) The firmware responds with the unique id of the time event.
4) When time event starts, the driver puts the frame in the
Aux queue.
Special care needs to be taken when the time events ends:
the queue needs to be cleaned-up.

Apparently fw/hw generates a corrupted QoS Control
Field in Qos NullFunc frames. The only way to
workaround this is to downgrade frames to
NullFunc. This should be okay since powersave is
done by fw/hw and these frames are only used for
CQM purposes (e.g. from hostapd to check if
station is still connected).
This doesn't fix any user visible bug that I know
of. It just prevents from sending out funky frames
on the air.

bcmgenet_wol_resume() will create an unbalanced clock state for the
wol_clk clock pointer since everywhere else in the code, we always call
clk_prepare_enable() and clk_disable_unprepare(). This function also
calls init_umac() which is neither correct nor necessary since
bcmgenet_resume() and bcmgenet_open() already does that.
Finally calling bcmgenet_wol_resume() in bcmgenet_open() is not correct,
since the interface would not have been able to put us in Wake-on-LAN
mode if it was not UP before.
