Deren WuandFelix Fietkau 5df6b26a9f wifi: mt76: connac: add eht support for tx power
Add eht field in struct mt76_power_limits for 802.11be power config.
The function stack size would be too big by eht adding in structure,
we also refactor mt76_connac_mcu_rate_txpower_band() to take dynamic
allocated memory instead.

This is a preliminary patch to support mt7925 driver.

Add support to report eht rx rate.
Note that extended fields for eht in mt76_rx_status will make the struct
size exceed the cb size, so make nss and band share the same u8.

Felix Fietkau f1e1e67d97 wifi: mt76: fix race condition related to checking tx queue fill status
When drv_tx calls race against local tx scheduling, the queue fill status checks
can potentially race, leading to dma queue entries being overwritten.
Fix this by deferring packets from drv_tx calls to the tx worker, in order to
ensure that all regular queue tx comes from the same context.

Note that mt7915 WA firmware only counts tx_packet for WED path, so driver
