Yeah, but WHY would you want to change the MAC? There are valid reasons to do so, but they are rarely ever used. Changing the MAC address doesn't follow any "standard" methods. It's going to be different from vendor to vendor, hence, you'll need to consult with the vendor of the card your using to get the methods they supply in their drivers.
