When networking service was up, it match output used re.search('inet6 .* scope link',
addr_output), because re.search checks for a match anywhere in the string:
5: ens10: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 52:54:00:97:3d:30 brd ff:ff:ff:ff:ff:ff
inet6 fe80::5054:ff:fe97:3d30/64 scope link tentative
valid_lft forever preferred_lft forever
It will make mistake for dhclient, because ip flag is tentative and
interface can't be bound:
error: cmd '/sbin/dhclient -6 -pf /run/dhclient6.ens10.pid -lf /var/lib/dhcp/dhclient6.ens10.leases ens10' failed: returned 1
