#define	nil_get_addr_req(nil_phone, device_id, address, data)   generic_get_addr_req(nil_phone, NET_NIL_ADDR, device_id, address, data)
	Returns the device local hardware address.
#define	nil_get_broadcast_addr_req(nil_phone, device_id, address, data)   generic_get_addr_req(nil_phone, NET_NIL_BROADCAST_ADDR, device_id, address, data)
	Returns the device broadcast hardware address.
#define	nil_send_msg(nil_phone, device_id, packet, sender)   generic_send_msg(nil_phone, NET_NIL_SEND, device_id, packet_get_id(packet), sender, 0)
	Sends the packet queue.
#define	nil_packet_size_req(nil_phone, device_id, packet_dimension)   generic_packet_size_req(nil_phone, NET_NIL_PACKET_SPACE, device_id, packet_dimension)
	Returns the device packet dimension for sending.
#define	nil_device_req(nil_phone, device_id, mtu, netif_service)   generic_device_req(nil_phone, NET_NIL_DEVICE, device_id, mtu, netif_service)
	Registers new device or updates the MTU of an existing one.
#define	nil_bind_service(service, device_id, me, receiver)   bind_service(service, device_id, me, 0, receiver);
	Creates bidirectional connection with the network interface layer module and registers the message receiver.
int	nil_device_state_msg (int nil_phone, device_id_t device_id, int state)
	Notifies the network interface layer about the device state change.
int	nil_received_msg (int nil_phone, device_id_t device_id, packet_t packet, services_t target)
	Passes the packet queue to the network interface layer.

Detailed Description

Network interface layer module interface.

The same interface is used for standalone remote device modules as well as for bundle device modules. The standalone remote device modules have to be compiled with the nil_remote.c source file. The bundle device modules with the appropriate network interface layer source file (eth.c etc.). The upper layers cannot be bundled with the network interface layer.
