How to give a MacVLAN port a fixed MAC address

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi,
I would like to define the mac address of the McFarland port as a fixed Mac, not randomly generated. Besides modifying the configuration file using uci:
uci set network.macvlan1.macaddr=xx:xx:xx:xx:xx:xx

Is there any other command to implement it?
