atomic host upgrade
we assume have four network on the host. the host network may like following.
-bash-4.2# brctl show
bridge name bridge id STP enabled interfaces
atomic0 8000.00e0b40f9fbb no enp3s0
atomic1 8000.00010a0ae7d8 no enp3s1
atomic2 8000.00e0b40f9fbc no enp4s0
atomic3 8000.00010a0ac65c no enp4s1
docker0 8000.02429bd02204 no
enpXXXX are phy NIC
atomic[0-3] are for this demo
docker0 is gen by atomic host
