netif struct

Generic data structure used for all lwIP network interfaces. The following fields should be filled in by the initialization function for the device driver: hwaddr_len, hwaddr[], mtu, flags

Syntax

struct netif;
Implemented in netif.h:260

Fields

next

pointer to next in linked list. Read more...

ip_addr

IP address configuration in network byte order. Read more...

netmask

No summary provided. Read more...

gw

No summary provided. Read more...

input

This function is called by the network device driver to pass a packet up the TCP/IP stack. Read more...

output

This function is called by the IP module when it wants to send a packet on the interface. This function typically first resolves the hardware address, then sends the packet. For ethernet physical layer, this is usually etharp_output(). Read more...

linkoutput

This function is called by ethernet_output() when it wants to send a packet on the interface. This function outputs the pbuf as-is on the link medium. Read more...
This function is called when the netif link is set to up or down. Read more...

state

This field can be set by the device driver and could point to state information for the device. Read more...

client_data

No summary provided. Read more...

mtu

maximum transfer unit (in bytes). Read more...

hwaddr

link level hardware address of this interface. Read more...

hwaddr_len

number of bytes used in hwaddr. Read more...

flags

flags (@see netif_flags). Read more...

name

descriptive abbreviation. Read more...

num

number of this interface. Used for if_api and netifapi_netif, as well as for IPv6 zones. Read more...

rs_count

Number of Router Solicitation messages that remain to be sent. Read more...

Examples

netif is referenced by 35 libraries and example projects.
