at76_dwork_hw_scan holds a mutex while calling ieee80211_scan_completed,
which then calls at76_config which needs the same mutex. This reworks
the ordering to not hold the lock while calling ieee80211_scan_completed.

Periodic RX interrupt needed with ICT interrupt to prevent RX race.
Sending RX interrupt require many steps to be done in the
the device:
1- write interrupt to current index in ICT table.
2- dma RX frame.
3- update RX shared data to indicate last write index.
4- send interrupt.
This could lead to RX race, driver could receive RX interrupt
but the shared data changes does not reflect that.
this could lead to RX race, RX periodic will solve this race

Add new lock to be used when accessing some registers. Also move
the register lock and iwl_grab_nic_access inside the function for register access. This
will prevent from forgetting to hold locks and nic access in the right way and make code
easier to maintain.
We over use the priv->lock spin lock and I guess we need to add new
one for Tx queue after that we might need to change most of these lock to
BH and just keep priv->lock as irq type.

'tpt' is a delta throughput (number of packets) and is corelated
to brightness of the LED. We already maintain a delta of packets in
rxtxpackets. There is no need to calculate this delta again which
was affecting the behaviour of LEDS.
Also add two new callback functions for ASSOCIATED/DISASSOCIATED states
where LED's will be *on* for associated state and *off* for disassociated state.

The scratch pad register is used to store firmware status after
firmware is downloaded and initialized. After firmware status is
verified OK, the same register is used to store RX packet length.
Hence the firmware status code is no longer valid afterwards.
SD8688 firmware introduces a new register for firmware status
which will never be overwritten.
Also add scratch_reg variable to if_sdio_card structure and
initialize it based on the model of the card during probe.

Some APs seem to drift away from the expected TBTT (timestamp %
beacon_int_in_usec differs quite a bit from zero) which can result in
us waking up way too early to receive a Beacon frame. In order to work
around this, re-configure the Beacon timers after having received a
Beacon frame from the AP (i.e., when we know the offset between the
expected TBTT and the actual time the AP is sending out the Beacon
frame).

The previous version used a simple loop to go through all Beacon
frames when determining the next TBTT and DTIM count. This is not too
bad for the case where the setup happens before timesync (i.e., very
small TSF), but this can become very heavy operation if a short Beacon
interval is used and the current TSF is large.
In preparation for a patch to update timer setup based on Beacon
timestamp, optimize this routine to take fixed time regardless of the
actual TSF value.

SD8688 is a WLAN/Bluetooth combo chip and both functions are supported
in a single firmware image. FUNC_INIT and FUNC_SHUTDOWN commands are
implemented to utilize the multiple function feature.
When SD8688 card is inserted, the firmware image should be downloaded
only once through either WLAN function (Libertas driver) or Bluetooth
function (Bluetooth driver).
This patch adds function init/shutdown for SD8688 WLAN function only.

Usually, the 16-bit rx length is read from scratch pad registers
with two CMD52 transactions:
SD8385: IF_SDIO_SCRATCH_OLD (0x80fe/0x80ff)
SD8686/SD8688: IF_SDIO_SCRATCH (0x34/0x35)
Alternatively, SD8688 firmware offers an enhanced method for driver
to read an 8-bit rx length (in units) with a single CMD52:
IF_SDIO_RX_UNIT 0x43 is read one time after firmware is ready.
IF_SDIO_RX_LEN 0x42 is read every time when rx interrupt is received.

mac80211 does not set PM field for normal data frames, so we need to
update that based on the current PS mode when using PS-Poll
(timeout=0) power save mode.
This allows the AP to remain in sync with our PS state. However, there
is still a potential race condition between PS state changes when
multiple TX queues are used and nullfunc and PS-Poll frames use
different queue. That corner case may need to be handled separately by
changing which queue is used either in ath9k or mac80211.

If we are trying to interpolate a curve with slope == 0, the return
value will always be the y-coordinate. In this code we are looping
until we reach a minimum y-coordinate on a line, which in the 0-slope
case can never happen, thus the loop never terminates.
The PCDAC steps come from the EEPROM and should never be equal, but
we should gracefully handle that case, so warn and bail out.

Currently all radios receive all traffic on the simulated air

the concept of grouping, which allows to assign a radio to
certain group. Only radios in the same group can 'see' each other.
Each bit in /debug/ieee80211/phy*/hwsim/group
represents one group. By default all radios belong to the same group "1",
e.g. bit 1 is set. Additionally a radio can belong to several groups.
