OK, I have added NetworkAddress property. You can download the updated driver using the same link
Though please note that in this build assigning the network adapter hardware address has a few limitations:
1) It should not be multicast address (addr[0] & 0x01 == 0)
2) It should not be broadcast address (FF-FF-FF-FF-FF-FF)
3) It should be marked as assigned by the local administrator (addr[0] & 0x2 == 1)
Example of valid address is 06-01-02-03-04-05
