TEST: prio_test (Test bonding option 'prio' with mode=1 monitor=arp_ip_target and primary_reselect=0) [ OK ]
TEST: prio_test (Test bonding option 'prio' with mode=1 monitor=arp_ip_target and primary_reselect=1) [ OK ]
TEST: prio_test (Test bonding option 'prio' with mode=1 monitor=arp_ip_target and primary_reselect=2) [ OK ]
TEST: prio_test (Test bonding option 'prio' with mode=1 monitor=miimon and primary_reselect=0) [ OK ]
