Ido, I am not so known to the selftests, so I am wondering why I don't
see either check_err or check_fail fail, whichever I use, when I think
they should and then they are not really checking...

local mac=10:20:30:30:20:10

$MZ $h1 -t udp -a $mac -b rand
bridge fdb show dev $swp1 | grep -q "$mac vlan 1 master br0
locked"
check_err $? "MAB station move: no locked entry on first
injection"

$MZ $h2 -t udp -a $mac -b rand
bridge fdb show dev $swp1 | grep -q "$mac vlan 1 master br0
locked"
check_err $? "MAB station move: locked entry did not move"

What is wrong here?

For a mv88e6xxx test I guess I can make a check to verify that this
driver is in use?
