The first patch fixed ns targets not work on hardware NIC when bonding
set arp_validate.

The second patch add a related selftest for bonding.

v4: Thanks Nikolay for the comments:
    use bond_slave_ns_maddrs_{add/del} with clear name
    fix comments typos
    remove _slave_set_ns_maddrs underscore directly
    update bond_option_arp_validate_set() change logic
v3: use ndisc_mc_map to convert the mcast mac address (Jay Vosburgh)
v2: only add/del mcast group on backup slaves when arp_validate is set (Jay Vosburgh)
    arp_validate doesn't support 3ad, tlb, alb. So let's only do it on ab mode.

  bonding: add ns target multicast address to slave device
  selftests: bonding: add ns multicast group testing
