83216e3988 of: net: pass the dst buffer to of_get_mac_address()
of_get_mac_address() returns a "const void*" pointer to a MAC address.
Lately, support to fetch the MAC address by an NVMEM provider was added.
But this will only work with platform devices. It will not work with
PCI devices (e.g. of an integrated root complex) and esp. not with DSA
ports.

There is an of_* variant of the nvmem binding which works without
devices. The returned data of a nvmem_cell_read() has to be freed after
use. On the other hand the return of_get_mac_address() points to some
static data without a lifetime. The trick for now, was to allocate a
device resource managed buffer which is then returned. This will only
work if we have an actual device.

Change it, so that the caller of of_get_mac_address() has to supply a
buffer where the MAC address is written to. Unfortunately, this will
touch all drivers which use the of_get_mac_address().

Usually the code looks like:

  const char *addr;
  addr = of_get_mac_address(np);
  if (!IS_ERR(addr))
    ether_addr_copy(ndev->dev_addr, addr);

This can then be simply rewritten as:

  of_get_mac_address(np, ndev->dev_addr);

Sometimes is_valid_ether_addr() is used to test the MAC address.
of_get_mac_address() already makes sure, it just returns a valid MAC
address. Thus we can just test its return code. But we have to be
careful if there are still other sources for the MAC address before the
of_get_mac_address(). In this case we have to keep the
is_valid_ether_addr() call.

The following coccinelle patch was used to convert common cases to the
new style. Afterwards, I've manually gone over the drivers and fixed the
return code variable: either used a new one or if one was already
available use that. Mansour Moufid, thanks for that coccinelle patch!

BSS_INFO_BASIC is never called alone with inactive state, which always
follows beacon offload disable, so keep it enabled throughout interfaces
life cycle. Inactive state also removes sta record of all connected
stations, thurs causes connection lost which defeats the purpose of CSA.

Lastly, this is especially an unexpected behavior that keeping mt7622
failing beacon buffer recyled when scanning channels.

bss_conf change is updated with active state only, so just overwrite it.

With threaded NAPI, the rx handler function is no longer bound to the CPU that
fired the interrupt, which significantly helps to spread the workload over
multiple CPUs, especially when multiple devices are using threaded NAPI at the
same time.
Exclude the tx handler from threaded NAPI by using a separate dummy netdev.
The work is small and short-lived enough that it makes more sense to run it in
softirq instead of creating a dedicated thread

4b36cc6b39 mt76: mt76x0: disable GTK offloading
When operating two VAP on a MT7610 with encryption (PSK2, SAE, OWE),
only the first one to be created will transmit properly encrypteded
frames.

All subsequently created VAPs will sent out frames with the payload left
unencrypted, breaking multicast traffic (ICMP6 NDP) and potentially
disclosing information to a third party.

Disable GTK offloading and encrypt these frames in software to
circumvent this issue. THis only seems to be necessary on MT7610 chips,
as MT7612 is not affected from our testing.

858ebf446b mt76: mt7615: support loading EEPROM for MT7613BE
EEPROM blobs for MT7613BE radios start with (little endian) 0x7663,
which is also the PCI device ID for this device. The EEPROM is required
for the radio to work at useful power levels, otherwise only the lowest
power level is available.

87fce88658 mt7601u: fix always true expression
Currently the expression ~nic_conf1 is always true because nic_conf1
is a u16 and according to 6.5.3.3 of the C standard the ~ operator
promotes the u16 to an integer before flipping all the bits. Thus
the top 16 bits of the integer result are all set so the expression
is always true.  If the intention was to flip all the bits of nic_conf1
then casting the integer result back to a u16 is a suitabel fix.

Interestingly static analyzers seem to thing a bitwise ! should be
used instead of ~ for this scenario, so I think the original intent
of the expression may need some extra consideration.

ae064fc0e3 mt76: fix tx skb error handling in mt76_dma_tx_queue_skb
When running out of room in the tx queue after calling drv->tx_prepare_skb,
the buffer list will already have been modified on MT7615 and newer drivers.
This can leak a DMA mapping and will show up as swiotlb allocation failures
on x86.

Fix this by moving the queue length check further up. This is less accurate,
since it can overestimate the needed room in the queue on MT7615 and newer,
but the difference is small enough to not matter in practice.

ba4590942e mt76: testmode: make tx queued limit adjustable
Originally, tx queued limit is set to 1000 to prevent from running out
of tx token. If a new testmode tx is triggered while the previous one
hasn't finished yet, we'll wait a period of time until tx_done equals to
tx_queued. Normally, current queued limit can finish in 10 seconds.

However, if ipg is configured to a larger value, less than 1000 packets
can be done in the default timeout period, which may lead to a crash
when a new testmode tx triggered.

To deal with this, make tx queued limit dynamically adjusted according
to ipg value.

1dac51269d mt7601u: check the status of device in calibration
When the usb device being plugged out, before ieee80211 gets to know the
hw being removed, it gets to know that the association status changed,
and thus ask for the device to do the calibration. This causes error as
the hw is absent.

This can be avoid by checking the status of the device before sending
the calibration request to the device.

Use the proper type for the queue ID variables to fix these warnings.
Additionally, rename the txq variable in mt7915_mcu_send_message to be
more neutral like mt7615_mcu_send_message.

f12758f6f9 mt76: mt7615: Fix fall-through warnings for Clang
In preparation to enable -Wimplicit-fallthrough for Clang, fix a
warning by replacing a /* fall through */ comment with the new
pseudo-keyword macro fallthrough; instead of letting the code fall
through to the next case.

Notice that Clang doesn't recognize /* fall through */ comments as
implicit fall-through markings.

When looking for a MAC address slot, start by using main BSSID slots 1-3,
afterwards use 16 repeater mode BSSID slots, then start using the slots
usually used for AP mode.

This search order should prevent unnecessary conflicts with AP mode interfaces
on the same PHY.

Note that two PHYs share global 32 omac slots with each other.

Fix that by adding while loop again. We need loop, not just single
check, to clean all pending entries.

Additionally move mt76_worker_disable/enable after !mt76_has_tx_pending()
as we want to tx_worker to run to process tx queues, while we wait for
exactly that.

I was a bit worried about accessing q->queued without lock, but
mt76_worker_disable() -> kthread_park() should assure this value will
be seen updated on other cpus.

In order to avoid keeping work like tx scheduling pinned to the CPU it was
scheduled from, it makes sense to switch from tasklets to kernel threads.

Unlike a workqueue, this one only allows one fixed worker function to be
executed by the worker thread. Because of that, there is less locking
and less code for scheduling involved.
This is important because the tx worker is scheduled often in a hot path

1daf2522fa mt76: mt7915: clean up station stats polling and rate control update
Queueing a per-sta work item from the tx free path can become very expensive
under load. This work is only supposed to pull rate control stats every
second and deal with rate control changes.

Additionally, the rate control update code was wrong, because it was
confusing bit masks and bit numbers in test_bit.

Fix this by introducing a dedicated device work item for rate control
updates, and by polling station stats from the phy mac work.
Stations requiring polling or rate control updates are added to lists
protected by dev->sta_poll_lock.

initial support for QCA6390 and IPQ6018 devices. But most of the
patches are cleanup: W=1 warning fixes, fallthrough keywords, DMA API
changes and tasklet API changes.

Major changes:

ath10k

* support SDIO firmware codedumps

* support station specific TID configurations

ath11k

* add support for IPQ6018

* add support for QCA6390 PCI devices

ath9k

* add support for NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 to improve PTK0
  rekeying

wcn36xx

* add support for TX ack

1808191dca mt7601u: Use fallthrough pseudo-keyword
Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

b4be5a53eb mt76: mt7915: use ieee80211_free_txskb to free tx skbs
Using dev_kfree_skb for tx skbs breaks AQL. This worked until now only
by accident, because a mac80211 issue breaks AQL on drivers with firmware
rate control that report the rate via ieee80211_tx_status_ext as struct
rate_info.

d1c9da9e4c mt76: mt7615: use v1 MCU API on MT7615 to fix issues with adding/removing stations
The implementation of embedding WTBL update inside the STA_REC update is buggy
on the MT7615 v2 firmware. This leads to connection issues after a station has
connected and disconnected again.

Switch to the v1 MCU API ops, since they have received much more testing and
should be more stable.

On MT7622 and later, the v2 API is more actively used, so we should keep using
it as well.
