The following commits:
commit c815fdebef ("wlcore: spi: Populate config firmware data")
commit d776fc86b8 ("wlcore: sdio: Populate config firmware data")
Populated the nvs entry for wilink6 and wilink7 only while it is
still needed for wilink8 as well.
This broke user space backward compatibility when upgrading from older
kernels, as the alternate mac address would not be read from the nvs that
is present in the file system (lib/firmware/ti-connectivity/wl1271-nvs.bin)
causing mac address change of the wlan interface.
This patch fix this and update the structure field with the same default
nvs file name that has been used before.
In addition, some distros hold a default wl1271-nvs.bin in the file
system with a bogus mac address (deadbeef...) that overrides the mac
address that is stored inside the device.
Warn users about this bogus mac address and use the internal mac address

ath.git patches for 4.14. Major changes:
ath10k
* initial UBS bus support (no full support yet)
* add tdls support for 10.4 firmware
ath9k
* add Dell Wireless 1802
wil6210
* support FW RSSI reporting
Unlike the other sections of the NVM, the hw section is in big-endian.
To read a value from it, we had to cast it to __be16. Fix that by
using __be16 * for the entire section.

We read the regulatory.lar_enabled field in iwl_fw_get_nvm() and store
it in nvm->lar_enabled, taking care of endianness. But then later we
read it again to pass the value to iwl_init_sbands() without handling
endianness. To solve this, simply reuse nvm->lar_enabled when calling
that function.

When we flush a queue, the packets will have a 'failed'
status but we shouldn't send a BAR. This check was missing.
Because of that, when we got an ampdu_action with
IEEE80211_AMPDU_TX_STOP_FLUSH, we started the following
ping pong with the firmware:
1) Set the station as 'draining'
2) Get a failed Tx status (DRAINED)
3) Send a BAR because of the failed Tx status
(loop of 2 and 3)
This loop wasn't endless since the BAR isn't sent on a
queue that would trigger a "nested" BAR.

If a time event is already scheduled when trying to schedule one for
channel switch, the code assumes the channel switch is already
scheduled and no further action is required.
However, it is possible that the scheduled time event is actually
for session protection (e.g. when the first beacon after association
contains the CSA IE). In this case the channel switch will not be
scheduled which will finally lead to disconnection.
Fix this by removing the old time event and schduling a new one for
the channel switch.

When we unmap a non-empty Tx queue, we need to free the
pages that we allocated for the headers in TSO flows.
This code existed for the 9000 device family, but somehow
it got left out when the new Tx path for the A000 devices
was written.

The TVQM tells us the initial write pointer for a queue,
but that write pointer is in WiFi sequence number unit
and not in TFD index unit. Which means that the write
pointer in the TVQM's response can be bigger than the
Tx queue ring size.
Fix that by modulo'ing the write pointer from the TVQM
with the Tx queue size.

One of the queue config params is the associated station id.
Hence the FW must know about the station prior to the queue allocation.
In a000 devices, allocating a queue without a valid station
results with assert 0x2B00.
In FW restart flow the queues are allocated before
adding the station so first add the station.

When an RX block-ack session times out, the firmware, which offloads
RX reordering but not the BA session negotiation, stops the session
but doesn't send a DELBA. This causes the the session to remain
active in the remote device, so no more BA sessions will be
established, causing a severe throughput degradation due to the lack
of aggregation.
Use the new ieee80211_rx_ba_timer_expired API when the ba session timer
expires, since this will tear down the ba session and also send a delba.
The previous API used is intended for drivers that offload the
addba/delba negotiation, but not the rx reordering, while our driver
does the opposite.
This patch depends on "mac80211: add api to start ba session timer
expired flow".

On devices starting from 8000 series, the host can no longer toggle
the LED through the CSR_LED_REG register, but must do it via the
firmware instead. Add support for this. Note that this means that
the LED cannot be turned on while the firmware is off, so using an
arbitrary LED trigger may not work as expected.

When we start an Rx A-MPDU session, we first get the AddBA
request, then we send an ADD_STA command to the firmware
that will reply with a BAID which is a hardware resource
that tracks the BA session.
This BAID will appear on each and every frame that we get
from the firwmare until the A-MPDU session is torn down.
In the Rx path, we look at this BAID to manage the
reordering buffer.
This flow is inherently racy since the hardware will start
to put the BAID in the frames it receives even if the
firmware hasn't sent the response to the ADD_STA command.
This basically means that the driver can get frames with
a valid BAID that it doesn't know yet.
When that happens, the driver used to WARN.
Fix this by simply not WARN in this case. When the driver
will know abou the BAID, it will initialise the relevant
states and the next frame with a valid BAID will refresh
them.

In AP mode, if a station is removed just as it is adding a new stream,
the queue in question will remain stopped and no more TX will happen
in this queue, leading to connection failures and other problems.
This is because under DQA, when tx is deferred because a queue needs
to be allocated, the mac queue for that TID is stopped until the new
stream is added. If at this point the station that this stream
belongs to is removed, all the deferred tx frames are purged, but the
mac queue is not restarted. As a result, all following tx on this
queue will not be transmitted.
Fix this by starting the relevant mac queues when the deferred tx
frames are purged.
