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

Fields

next: *mut netif

pointer to next in linked list

ip_addr: ip_addr

IP address configuration in network byte order

netmask: ip_addr

gw: ip_addr

ip6_addr: [ip_addr; 3]

Array of IPv6 addresses for this netif.

ip6_addr_state: [u8; 3]

The state of each IPv6 address (Tentative, Preferred, etc). @see ip6_addr.h

ip6_addr_valid_life: [u32; 3]

Remaining valid and preferred lifetime of each IPv6 address, in seconds. For valid lifetimes, the special value of IP6_ADDR_LIFE_STATIC (0) indicates the address is static and has no lifetimes.

ip6_addr_pref_life: [u32; 3]

input: Option<unsafe extern "C" fn(_: *mut pbuf, _: *mut netif) -> i8>

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

output: Option<unsafe extern "C" fn(_: *mut netif, _: *mut pbuf, _: *const ip4_addr) -> i8>

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()

linkoutput: Option<unsafe extern "C" fn(_: *mut netif, _: *mut pbuf) -> i8>

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.

output_ip6: Option<unsafe extern "C" fn(_: *mut netif, _: *mut pbuf, _: *const ip6_addr) -> i8>

This function is called by the IPv6 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 ethip6_output()

state: *mut c_void

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

client_data: [*mut c_void; 3]

hostname: *const i8

mtu: u16

maximum transfer unit (in bytes)

mtu6: u16

maximum transfer unit (in bytes), updated by RA

hwaddr: [u8; 6]

link level hardware address of this interface

hwaddr_len: u8

number of bytes used in hwaddr

flags: u8

flags (@see @ref netif_flags)

name: [i8; 2]

descriptive abbreviation

num: u8

number of this interface. Used for @ref if_api and @ref netifapi_netif, as well as for IPv6 zones

ip6_autoconfig_enabled: u8

is this netif enabled for IPv6 autoconfiguration

rs_count: u8

Number of Router Solicitation messages that remain to be sent.

igmp_mac_filter: Option<unsafe extern "C" fn(_: *mut netif, _: *const ip4_addr, _: u32) -> i8>

This function could be called to add or delete an entry in the multicast filter table of the ethernet MAC.

mld_mac_filter: Option<unsafe extern "C" fn(_: *mut netif, _: *const ip6_addr, _: u32) -> i8>

This function could be called to add or delete an entry in the IPv6 multicast filter table of the ethernet MAC.

loop_first: *mut pbuf

loop_last: *mut pbuf

loop_cnt_current: u16

reschedule_poll: u8
