Detailed Description

lwIP network interface abstraction

Function Documentation

netif_add()

struct netif* netif_add	(	struct netif *	netif,
		struct ip_addr *	ipaddr,
		struct ip_addr *	netmask,
		struct ip_addr *	gw,
		void *	state,
		err_t(*)(struct netif *netif)	init,
		err_t(*)(struct pbuf *p, struct netif *netif)	input
	)

Add a network interface to the list of lwIP netifs.

Parameters

netif	a pre-allocated netif structure
ipaddr	IP address for the new netif
netmask	network mask for the new netif
gw	default gateway IP address for the new netif
state	opaque data passed to the new netif
init	callback function that initializes the interface
input	callback function that is called to pass ingress packets up in the protocol layer stack.

Returns

netif, or NULL if failed.
