> The driver was not correctly handling calls to its ndo_set_mac_address
> method. It did not properly check to see if the override would be allowed by
> the PF driver, and never removed the old address from its filter list.
> 
> Add a new flag to the adapter struct which is set if the MAC address is
> assigned by the PF. Check this flag and don't allow the MAC address to be
> changed if it is set. Search for and properly remove the filter for the old MAC
> address when the new one is set.
