The output shows like:
74:e1:e1:2c:4f:18 dev eth8 vlan 1 master br0 extern_learn offload sticky 
locked blackhole

"sticky" will of course become "permanent", but I can still make it more 
resilient by piping grep.

I suppose that I will keep the "sticky_no_roaming" test even though it 
is not really needed here anymore?
