```
The interface veth99 entered the configured state after 5 seconds, but
at the same time, the `wait_online()` in the test script considered the
test failed.
The function `wait_online()` first invokes
`systemd-networkd-wait-online` with `--timeout=20`, then check setup
states of interfaces with 5 seconds timeout. So, the failure suggests
that `systemd-networkd-wait-online` finishes immediately, as the state
file was not updated when it is invoked, and thus it handles the
interface veth99 already in the configured state.
