The following commits:
commit c815fdeb ("wlcore: spi: Populate config firmware data")
commit d776fc86 ("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

Merge tag 'iwlwifi-next-for-kalle-2017-08-18' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next

Third set of iwlwifi patches for 4.14

* Work for the upcoming A000 device family continues;
* Improvements in debugging;
* A couple of improvements in block-ack sessions;
* Some fixes for channel switch;
* A workaround for a HW data bug;
* Some FW API updates;
* General fixes and cleanups here and there.

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.

The OTP in some SKUs have erroneously allowed 40MHz and 80MHz channels
in the 5.2GHz band.  The firmware has been modified to not allow this
in those SKUs, so the driver needs to do the same otherwise the
firmware will assert when we try to use it.

The code did not consider the case that the channel switch counter
is <= 1, which would result with an inaccurate calculation of the
time event apply time.

As the specification states that in case of counter == 0 the switch
occurs at any time after the reception the frame, and for counter == 1
the switch would happens before the next TBTT, schedule the time
event immediately.

These messages are not reporting a real error, just the fact that the

Currently these messages are presented to the user during boot if there
is no bootsplash covering the console, even when booting the kernel with

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.

There's no need to differentiate an INIT that ended early because of
RFKILL from one that succeded.  Additionally, if INIT fails later,
