Lorenzo BianconiandFelix Fietkau 06c917faeb mt76: introduce mt76_sw_queue data structure 
Introduce mt76_sw_queue data structure in order to support new
chipsets (e.g. mt7615) that have a shared hardware queue for all traffic

Arnd BergmannandFelix Fietkau d1bc504955 mt76: fix building without CONFIG_LEDS_CLASS 
When CONFIG_LEDS_CLASS is disabled, or it is a loadable module while
mt76 is built-in, we run into a link error:

drivers/net/wireless/mediatek/mt76/mac80211.o: In function `mt76_register_device':
mac80211.c:(.text+0xb78): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `devm_of_led_classdev_register'

We don't really need a hard dependency here as the driver can presumably
work just fine without LEDs, so this follows the iwlwifi example and
adds a separate Kconfig option for the LED support, this will be available
whenever it will link, and otherwise the respective code gets left out from
the driver object.

There is some code in the mac80211 tx status processing code that could

Felix Fietkau 9d59d2a53f mt76: add support for reporting tx status with skb 
MT76x2/MT76x0 has somewhat unreliable tx status reporting, and for that
reason the driver currently does not report per-skb tx ack status at all.
This breaks things like client idle polling, which relies on the tx ack
status of a transmitted nullfunc frame.

This patch adds code to report skb-attached tx status if requested by
mac80211 or the rate control module. Since tx status is polled from a
simple FIFO register, the code needs to account for the possibility of
tx status events getting lost.

The code keeps a list of skbs for which tx status is required and passes
them to mac80211 once tx status has been filled in and the DMA queue is
done with it.
If a tx status event is not received after one second, the status rates
are cleared, and a succesful ACK is indicated to avoid spurious disassoc
during assoc or client polling.

Kees CookandFelix Fietkau 788becd861 treewide: devm_kzalloc() -> devm_kcalloc() 
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

Enable the use of CQM_RSSI_LIST with mt76-devices. The change has been
tested with the mt7602, mt7603 and mt7621 PCI wifi-cards. I passed a
list of RSSI thresholds to the driver, and when disconnecting/connecting
the antenna(s) I got an event each time the RSSI went above/below a
threshold.

While I have not been able to test the change with any of the mt76
USB-devices (no access to a device), the RX RSSI management code is
shared between the two device types. Thus, CQM should also work with the
mt76 USB-devices.

Felix Fietkau ca5cc9a478 mt76: fix concurrent rx calls on A-MPDU release 
Add a spinlock in mt76_rx_complete. Without this, multiple stats updates
could happen in parallel, which can lead to deadlocks. There are
probably more corner cases fixed by this change.

Felix Fietkau f515dfcca1 mt76: implement AP_LINK_PS 
With software A-MPDU reordering in place, frames that notify mac80211 of
powersave changes are reordered as well, which can cause connection
stalls. Fix this by implementing powersave state processing in the
driver.
