kernel test robot <[email protected]> found the following issue
and Kalle Valo forwarded it to Linux wireless.
drivers/net/wireless/mediatek/mt76/pci.c:8:6:
warning: no previous prototype for 'mt76_pci_disable_aspm'
Fix this by adding the missing include of mt76.h as Kalle
suggested.

While looking at the ETSI regulatory domain definitions
and a patch, which allows more channels for ath10k, I also
checked the channels allowed for mt76.
ETSI regulations would possibly allow to add channels 32, 68,
96, 144, 169 and 173. IEEE 802.11-2016 defines no operating class
for channels 32, 68 and 96. This leaves us channels 144, 169 and 173,
which are included in this patch.
I tested 169 and 173 with a mt76 based USB dongle (AVM AC 860) and they
worked fine. If I saw that right, these channels are also covered by
register definitions inside the driver.
Channel 144 should also work, but gets disabled by the kernel as of now.

Use larger batches for usb copy to speed this operation up. Otherwise it
would be too slow for copying new beacons or broadcast frames over usb.
Assure, that always a multiple of 4 Bytes is copied, as outlined in
850e8f6fbd "mt76: round up length on mt76_wr_copy" from Felix Fietkau.

This patch removes a mt76_wr_copy call from the beacon path to hw.
The skb which is used in this place gets therefore build with txwi
inside its data. For mt76 usb drivers, this saves one synchronuous
copy call over usb, which lets the beacon work complete faster.
In mmio case, there is not enough headroom to put the txwi into the
skb, it is therefore using an additional mt76_wr_copy, which is fast
over mmio. Thanks Stanislaw for pointing this out.

On adding vifs the idx can become 1 + (7 & 7) = 8 for APs.
Check against that, as only AP vif idx 0-7 is possible.

Sending beacons to the hardware always happens in batches. In order to
speed up beacon processing on usb devices, this patch splits out common
code an calls it only once.
Beacons are sequentially written into the beacon memory area, by
tracking its usage with the dev->beacon_data_count. For MBSS support
and buffered traffic dev->beacon_data_count is used to create the bypass
mask.
The code is also adapted for the mmio part of the driver, but should not
have any performance implication there.
MBSS tests were performed with AVM AC860 USB NIC with temporary support
for 5 BSS'. Different combinations of active vifs were created and
brought up. Afterwards connection and data transfer was tested for the
announced BSS'.

mt76 hw does not send beacons from beacon slots, if the corresponding
bitmask is set accordingly. Therefore we can omit clearing the beacon
memory. Clearing uses many usb calls, if usb drivers are used. These
calls unnecessarily slow down the beacon tasklet. Thanks to Stanislaw
Gruzska for pointing this out.

Before this patch, mt76 handled rx traffic for all TIDs equally,
when released from reorder buffer early. This patch uses an AC specific
reorder timeout, in order to release partial aggregated frames for video
ACs earlier. Voice ACs are currently not aggregated (thanks to Felix for
this hint). For example, ath10k also uses AC specific reorder timeouts
(reported by firmware in that case).
