Julien Fortin 038136754c addons: bond: bond mac should always be inherited from it's first slave ...

check if the bond mac address is correctly inherited from it's
first slave. There's a case where that might not be happening:
$ ip link show swp1 | grep ether
   link/ether 08:00:27:04:d8:01 brd ff:ff:ff:ff:ff:ff
$ ip link show swp2 | grep ether
   link/ether 08:00:27:04:d8:02 brd ff:ff:ff:ff:ff:ff
$ ip link add dev bond0 type bond
$ ip link set dev swp1 master bond0
$ ip link set dev swp2 master bond0
$ ip link show bond0 | grep ether
   link/ether 08:00:27:04:d8:01 brd ff:ff:ff:ff:ff:ff
$ ip link add dev bond1 type bond
$ ip link set dev swp1 master bond1
$ ip link show swp1 | grep ether
   link/ether 08:00:27:04:d8:01 brd ff:ff:ff:ff:ff:ff
$ ip link show swp2 | grep ether
   link/ether 08:00:27:04:d8:01 brd ff:ff:ff:ff:ff:ff
$ ip link show bond0 | grep ether
   link/ether 08:00:27:04:d8:01 brd ff:ff:ff:ff:ff:ff
$ ip link show bond1 | grep ether
   link/ether 08:00:27:04:d8:01 brd ff:ff:ff:ff:ff:ff
$
ifupdown2 will automatically correct and fix this unexpected behavior
