The driver sends an action frame down and waits for a completion signal
triggered by the received BRCMF_E_ACTION_FRAME_OFF_CHAN_COMPLETE event
to continue the process. However, the action frame could be transmitted
either on the current channel or on an off channel. For the on-channel
case, only BRCMF_E_ACTION_FRAME_COMPLETE event will be received when
the frame is transmitted, which make the driver always wait a full
timeout duration. This patch has the completion signal be triggered by
receiving the BRCMF_E_ACTION_FRAME_COMPLETE event for the on-channel
case.

Finding a common channel to send an action frame out is required for
some action types. Since a loop with several scan retry is used to find
the channel, a short wait time could be considered for each attempt.
This patch reduces the wait time from 1500 to 450 msec for each action
frame scan.

brcmfmac is a FullMAC driver and it implements/uses cfg80211 interface
for stations management. At the same time it doesn't receive or pass up
management frames.
This flag indicates that authenticator doesn't have to subscribe to or
handle management frames. Some authenticators (e.g. hostapd) were
working with brcmfmac thanks to some extra assumptions. This commit

The firmware does not respond ARP request and causes ping failed with
following steps.
1. Bring up inteface
ifconfig wlan0 up or start wpa_supplicant
2. Set the IP address
ifconfig wlan0 192.168.100.10
3. Bring down interface or
ifconfig wlan0 down or kill wpa_supplicant
4. Bring up inteface again and set the same IP address
5. Connect to AP(192.168.100.1) and ping to AP will be failed.
FMAC clears arp_hostip when bringing down the interface, but not set it
back if setting the same IP address. We are able to see the IP address
in interface info(inconfig wlan0) but the ping still cannot work because
the firmware ARP offload does not respond the ARP request.
Because of that, we remove "arp_hostip_clear" from function
"brcmf_netdev_stop"

The correct operation is to just delete those clock nodes belonged
to the device being detached, to avoid this case, we can add a device
point which can be assigned to device during attach_dev phase, then
in detach_dev phase, check the device pointer to make sure ONLY delete
those clock nodes belonged to its own and keep other clock nodes in the
same power domain there.

The quality selection bitfield is represented as following:
* Medium» 0 0 0
* High»» 0 0 1
* Very Low 2» 1 0 0
* Very Low 1» 1 0 1
* Very Low 0» 1 1 0
* Low» » 1 1 1
One might notice that from High to Very Low 2 quality there is
a gap of 2 (010 and 011) are missing. In the previous implementation
of amixer control, when you are selecting other quality than
the default mode, the value will always jump from High to Low
with a 2 step and will not be able to go back to a previous value.
The solution was to add two "N/A" undefined values in the
selection texts since those two values are marked as reserved
in the micfil RM.
The alternative was to write custom get and put functions to
only do the translation but the aproach in this patch is easier
to understand and less error prone.

Hardware Voice Activity Detector (HWVAD) is a block responsible for
detect voice activity in a channel selected by the user and it can be
configured in Envelope-based or Energy-based mode. Optionally, a
Zero-Crossing Detector can be enabled to improve the voice detection.
To enable hwvad from userspace there is a interface and you should write
the number of channels in /sys/devices/platform/30080000.micfil/hwvad/enable
to enable the hardware voice activity detection for micfil or 0
to disable it.
When voice activity is detected, an udev event will be generated:
"EVENT=PDM_VOICE_DETECT" and hwvad will be disabled afterwards.
