If we know that we have an encrypted link (based on having had
a key configured for TX in the past) then drop all data frames
in the key selection handler if there's no key anymore.
This fixes an issue with mac80211 internal TXQs - there we can
buffer frames for an encrypted link, but then if the key is no
longer there when they're dequeued, the frames are sent without
encryption. This happens if a station is disconnected while the
frames are still on the TXQ.
Detecting that a link should be encrypted based on a first key
having been configured for TX is fine as there are no use cases
for a connection going from with encryption to no encryption.
With extended key IDs, however, there is a case of having a key
configured for only decryption, so we can't just trigger this
behaviour on a key being configured.

The calibration patches for MT7620 unnecessarily export symbols and
populate never accessed function pointers. Remove all that and make
functions static as the only place where each of those functions is
called is within rt2800lib.c.
Also make code more readable by fixing indentation, removing
unnecessary parantheses and simplifying some instructions using

This patch adds 'qca,gpio-mask=<u32>' device tree property to ath9k node.
This optional setting is a hack and should only be used in very special
(and rare) cases when a button or LED is wired to a GPIO pin normally
masked out (due to being one-way etc). Netgear WNDR4300 v2 is one such
example - it uses GPI9 for RFKILL.
See ath9k/reg.h *_GPIO_MASK constants.
Use with caution and expect to see stream of kernel warnings if wrong
mask value is provided.

The Owl Loader (named after the codename that Atheros gave

This patch removes the "misc" driver OpenWrt had and adds
the remaining differences against the version that ships
with 5.4-rc1 into a separate "120-owl-loader-compat.patch"
file that can be cut down once AR71XX is being dealt with.
Note: I decided to keep the existing (kmod-)owl-loader

the kmod package will be called ath9k_pci_owl_loader.ko

The QCA953x only supports 25 MHz refclk, however some OEMs set an

Hence remove errornous line 5281 to make the driver actually
execute the correct initialization routine for MT7620 chips.
As it was requested by Stanislaw Gruszka remove setting values of
MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO
power-safe mode (which is disabled), hence we can drop setting it.
TX_PIN_CFG is set correctly in other functions, and as setting this
value breaks some devices, rather don't set it here during init, but
only modify it later on.

In non-ETSI regulatory domains scan is blocked when operating channel
is a DFS channel. For ETSI, however, once DFS channel is marked as
available after the CAC, this channel will remain available (for some
time) even after leaving this channel.
Therefore a scan can be done without any impact on the availability
of the DFS channel as no new CAC is required after the scan.
Enable scan in mac80211 in these cases.

Close cooperation with Lorenzo Bianconi resulted
in these patches which fix all remaining seen issues
when using dynack.
Fix link losses when:
- Late Ack's are not seen or not present
- switching from too low static coverage class to dynack on a live link
These are fixed by setting the Ack Timeout/Slottime to
the max possible value for the currently used channel width when
a new station has been discovered.
When traffic flows, dynack is able to adjust to optimal values
within a few packets received (typically < 1 second)
These changes have been thoroughly tested on ~60 offshore devices
all interconnected using mesh over IBSS and dynack enabled on all.
Distances between devices varied from <100m up to ~35km
