options 8852au rtw_country_code=GR
# Initially it will use USB2.0 mode, which will limit 5G 11ac throughput
# (USB2.0 bandwidth only 480Mbps => throughput around 240Mbps)
# with modprobe options it will switch to USB3.0 mode at initial driver load
#
options 8852au rtw_switch_usb_mode=1
#
#
#
### TODO: real time change usb2.0/3.0 mode
#
### usb2.0 => usb3.0
#
