Set a network interface as the default network interface used to output all packets for which no specific route is found. Send an IP packet to be received on the same netif loopif-like. These can be changed later. Called by a driver when its link goes down. Add a network interface to the list of lwIP netifs. Returns netif, or NULL if failed. The status callback will be called anytime the interface is brought up and down.

Add a network interface to the list of lwIP netifs. When the IP stack tries to route the packet, if it cannot determine the right interface to use, it will send it to the default interface.

The user specifies an IP netaork for the interface, its net mask, and gateway address see IP stack for more details. The final parameter input is lsip function that a driver will call when it has received a new nettwork.

These can be changed later. 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.

In other words, the functions only work when the netif driver is implemented correctly! Therefore, before you can use the interface, you must bring it up. Bring an interface down, disabling any traffic processing.

This can be accomplished depending on how the interface gets its IP address. The list of network interfaces. For example, if you would like to log the IP address chosen by DHCP when it has got one, and know when this address changes, nefwork you can use the status callback hook.
