- %description:
- In this test the server shuts down immediately after (t = 0.0s) the starting and reboots
- at t = 190s. Client acts according to its default behavior and starts sending DHCPDISCOVER
- messages via UDP broadcasts.
- As the client got no responses within its default timeout (60s) it periodically retransmits
- the DHCPDISCOVER message.
- In this scenario, server reboots at 190s so client has to retransmit DHCPDISCOVER four times
- before its first success.
