The implementation of mac_addr_set() through mac_addr_remove() and mac_addr_add() is very creative, but it may not work for devices other than igb/ixgbe. I will release a patch latter to add hooks on igb and ixgbe(). Just want to keep this interface clean and not to be confined to igb/ixgbe characteristics.
