Subject: [PATCHv3 net 2/2] selftests: bonding: add ns multicast group testing
Add a test to make sure the backup slaves join correct multicast group
when arp_validate enabled and ns_ip6_target is set. Here is the result:
TEST: arp_validate (active-backup ns_ip6_target arp_validate 0) [ OK ]
TEST: arp_validate (join mcast group) [ OK ]
TEST: arp_validate (active-backup ns_ip6_target arp_validate 1) [ OK ]
TEST: arp_validate (join mcast group) [ OK ]
TEST: arp_validate (active-backup ns_ip6_target arp_validate 2) [ OK ]
TEST: arp_validate (join mcast group) [ OK ]
TEST: arp_validate (active-backup ns_ip6_target arp_validate 3) [ OK ]
TEST: arp_validate (join mcast group) [ OK ]
TEST: arp_validate (active-backup ns_ip6_target arp_validate 4) [ OK ]
TEST: arp_validate (join mcast group) [ OK ]
TEST: arp_validate (active-backup ns_ip6_target arp_validate 5) [ OK ]
TEST: arp_validate (join mcast group) [ OK ]
TEST: arp_validate (active-backup ns_ip6_target arp_validate 6) [ OK ]
TEST: arp_validate (join mcast group) [ OK ]
