For this issue, similar with the wait_for_if_up,
Probably when this scripts is called `ip route show` show nothing
because there's still no route added. In this case we should not
return 0
I will update the two patch like "[ -z "${li##*state UP*}" ]",
and check [ -z "$li" ] as well for the nul case
