---------------------------

ANBZ: #3666

This is achieved by broadcasting ARP or ND packets to all of its slave
devices on transmit side. The switch will take further actions based on
proper configuration.

A new sysctl knob "net.bonding.broadcast_arp_or_nd" is introduced which
controls the behaviour of broadcasting.
