Internetwork layer module interface
This interface is used by other modules.
static int	il_device_state_msg (int il_phone, device_id_t device_id, device_state_t state, services_t target)
	Notifies the internetwork layer modules about the device state change.
static int	il_received_msg (int il_phone, device_id_t device_id, packet_t packet, services_t target)
	Notifies the internetwork layer modules about the received packet/s.
static int	il_mtu_changed_msg (int il_phone, device_id_t device_id, size_t mtu, services_t target)
	Notifies the internetwork layer modules about the mtu change.
