727685c317 mac80211: rt2x00: define RF5592 in init_eeprom routine
Make sure RF5592 is set for RT5592 chip which apparently sometimes
doesn't have RF defined (but always comes with RF5592).
This patch was originally submitted on linux-wireless by
Tom Psyborg <pozega.tomislav@gmail.com> but got rejected.
Turns out the patch is actually needed.

870588b6eb mac80211: ath9k: enable MFP capability unconditionally
ath9k will already fallback on software-crypto for chipsets not
supporting IEEE802.11w (MFP). So advertising MFP is not dependent
on disabling HW crypto for all traffic entirely.

Tested on Sonicwall SonicPoint Ni (AR9132)

a002a24536 mac80211: rt2x00: backport patch enabling MFP
From: Rui Salvaterra <rsalvaterra@gmail.com>
Date: Mon, 25 May 2020 14:49:07 +0100
Subject: [PATCH] rt2800: enable MFP support unconditionally

This gives us WPA3 support out of the box without having to manually disable
hardware crypto. The driver will fall back to software crypto if the connection
requires management frame protection.

066ec97167 mac80211: ath10k: increase rx buffer size to 2048
Before, only frames with a maximum size of 1528 bytes could be
transmitted between two 802.11s nodes.

For batman-adv for instance, which adds its own header to each frame,
we typically need an MTU of at least 1532 bytes to be able to transmit
without fragmentation.

This patch now increases the maxmimum frame size from 1528 to 1656
bytes.

Tested with two ath10k devices in 802.11s mode, as well as with
batman-adv on top of 802.11s with forwarding disabled.

Fix originally found and developed by Ben Greear.

0f1b5ce2f5 mac80211: drop data frames without key on encrypted links
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.

4a0a1fc91c mac80211: ath9k: add GPIO mask dts property
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

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.

Note: I decided to keep the existing (kmod-)owl-loader

the kmod package will be called ath9k_pci_owl_loader.ko

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.

is a DFS channel. For ETSI, however, once DFS channel is marked as
available after the CAC, this channel will remain available (for some

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.

This backport fixes high latency (>100ms) on the WiFi link when using a
QCA988x Wave 1 radio. The ath10k-ct driver is not affected by this bug
from my testing, hence why it hasn't been discovered earlier.

Initialize last_reset variable to INITIAL_JIFFIES, otherwise it is not
possible to test H/W reset for first 5 minutes of system run.

a58bfb7377 mac80211: rt2x00: revert commit causing regression in 5GHz band
From: Stanislaw Gruszka <sgruszka@redhat.com>
This reverts commit 9ad3b55654455258a9463384edb40077439d879f.

As reported by Sergey:

"I got some problem after upgrade kernel to 5.2 version (debian testing
linux-image-5.2.0-2-amd64). 5Ghz client  stopped to see AP.
Some tests with 1metre distance between client-AP: 2.4Ghz  -22dBm, for
5Ghz - 53dBm !, for longer distance (8m + walls) 2.4 - 61dBm, 5Ghz not
visible."

It was identified that rx signal level degradation was caused by
9ad3b5565445 ("rt2800: enable TX_PIN_CFG_LNA_PE_ bits per band").
So revert this commit.

5cc942a80e ath9k: backport dynack improvements
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
