2020-07-21mt76: mt7663u: sync probe sampling with rate configurationLorenzo Bianconi
On usb device rate configuration for sampling is performed relying on a workqueue since it is not possible to access the device in the interrupt context. Move the configuration of the probe_rate flag in the workqueue in order to keep probe sampling in sync with actual rate configuration Fixes: eb99cc95c3b6 ("mt76: mt7615: introduce mt7663u support") Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-07-21mt76: mt7615: schedule tx tasklet and sta poll on mac tx freeFelix Fietkau
Unlike on earlier chips, DMA completion on MT7615 does not imply actually having sent out any packets. Since AQL will prevent filling the hardware queues and will only allow more packets to be passed to the driver after tx completion, it makes much more sense to schedule the tx tasklet there.

2020-07-21mt76: allow more channels, allowed in ETSI domainMarkus Theil
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.
