The NIC is put in runtime suspend status when there is no cable connected.
As a result, it is safe to keep non-wakeup NIC in runtime suspended during
s2ram because the system does not rely on the NIC plug event nor WoL to wake
up the system. Besides that, unlike the s2idle, s2ram does not need to
manipulate S0ix settings during suspend.
