> 
> The RTW88 chipsets have four different priority queues in hardware. For
> the USB type chipsets the packets destined for a specific priority queue
> must be sent through the endpoint corresponding to the queue. This was
> not fully understood when porting from the RTW88 USB out of tree driver
> and thus violated.
> 
> This patch implements the qsel to endpoint mapping as in
> get_usb_bulkout_id_88xx() in the downstream driver.
> 
> Without this the driver often issues "timed out to flush queue 3"
> warnings and often TX stalls completely.
