Hello Songxiang,
Sorry, we do not provide MAC address production tools!
Bascially, you should buy MAC address from IEEE organization at first. Then make a solution for programing MAC address to board. For the operation of MAC address, you can do like this:
1. Setting it to u-boot environment.
2. Save it in eFUSE
3. Setting it in linux appliation.
