Merge pull request #33595 from freehan/fix-reboot-ifdownup
Automatic merge from submit-queue try to use ifdown/ifup if available Tried this on both ContainerVM and GCI image. `ip link set eth0 down` is too destructive for containerVM. It could not recover with correct network setup hence failing the test. Need to use ifdown/ifup on containerVM. reference: http://serverfault.com/questions/603906/ip-link-set-not-assigning-ip-address-but-ifup-does
