Sorry, I don't follow what you are talking about. What are you trying to do related to the mac address? Are you spoofing the mac address with calls like?
ifconfig eth0 hw ether 00:11:22:33:44:55
If so, this is unrelated to the udev rule which should be run before the above and use the real mac address of the device.
