When do arping, the interface need to be specified. Or we will
get error: Interface "lo" is not ARPable. And the test failed.
]# ./arp_ndisc_untracked_subnets.sh
    TEST: test_arp:  accept_arp=0                                       [ OK ]
    TEST: test_arp:  accept_arp=1                                       [FAIL]
    TEST: test_arp:  accept_arp=2  same_subnet=0                        [ OK ]
    TEST: test_arp:  accept_arp=2  same_subnet=1                        [FAIL]

After fix:
]# ./arp_ndisc_untracked_subnets.sh
    TEST: test_arp:  accept_arp=0                                       [ OK ]
    TEST: test_arp:  accept_arp=1                                       [ OK ]
    TEST: test_arp:  accept_arp=2  same_subnet=0                        [ OK ]
    TEST: test_arp:  accept_arp=2  same_subnet=1                        [ OK ]
