If the ethernet link is dropped without a DHCP socket, the interface IP address is cleared. However, because DHCP is not enabled, there is no means of re-acquiring an IP, so the stack will become unresponsive.

We should only clear the IP of the interface if a DHCP socket is present, since we could then re-acquire an address.
