When the firmware asserts, we restart the device and reset
the relevant data we hold in the driver. BT Coex data was
not reset and because of that, the driver wouldn't
reconfigure the firmware properly after firmware restart.

When we associate, we may have heard the beacon before the

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.

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.

Add new AUX ROC command that is intended for HS2.0 purposes.
It is used to send ANQP requests on a specific channel.

This command requests the firmware to trigger a time event
and remain on a certain channel for a given duration.
Triggering the time event is done by using the Aux
Framework in the firmware, and makes use of the Aux station
(similarly to scan).

These calls make sure the device is out of d0i3,

the refs_bitmap to a ref counter, so multiple refs

In managed mode if the driver is getting a re-associate command
from cfg80211, driver deauthenticates with the AP internally and
sends a disconnected event to cfg80211 before completion of its
association process. The disconnected event then modifies the
SSID length as wdev->ssid_len = 0. So, upon receiving the connect
result event from driver, cfg80211 is unable to get that BSS from
the device's BSS list and generates the following WARN_ON message.

WARNING: CPU: 0 PID: 857 at net/wireless/sme.c:658
         __cfg80211_connect_result+0x3a6/0x3e0 [cfg80211]()

Avoid re-association while the device is already associated to a
network. Also remove the internal deauthentication from the
association path.

Packets originally buffered for the regular hardware tx queues can end
up being transmitted through the U-APSD queue (via PS-Poll or U-APSD).
When packets are dropped due to retransmit failures, the pending frames
counter is not always updated properly.
Fix this by keeping track of the queue that a frame was accounted for in
the ath_frame_info struct, and using that on completion to decide
whether the counter should be updated.
This fixes some spurious transmit queue hangs.
