====================
bonding: use correct ether type for alb

There have been reports that, while using the ETH_P_LOOP ether type
(0x0060), the ether type is treated as its packet length.

To avoid that and to not break already existing apps - add new ether type
ETH_P_LOOPBACK that contains the correct id - 0x9000.
