void ip_input	(	struct pbuf *	p,
		struct netif *	inp
	)

This function is called by the network interface device driver when an IP packet is received.

The function does the basic checks of the IP header such as packet size being at least larger than the header size etc. If the packet was not destined for us, the packet is forwarded (using ip_forward). The IP checksum is always checked.

Finally, the packet is sent to the upper layer protocol input function.

Parameters:

	p	the received IP packet (p->payload points to IP header)
	inp	the netif on which this packet was received

Returns:

ERR_OK if the packet was processed (could return ERR_* if it wasn't processed, but currently always returns ERR_OK)
