Detailed Description

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

Member Data Documentation

◆ flags

u8_t netif::flags

flags (see NETIF_FLAG_ above)

◆ gw

struct ip_addr netif::gw

◆ hwaddr

u8_t netif::hwaddr[NETIF_MAX_HWADDR_LEN]

link level hardware address of this interface

◆ hwaddr_len

u8_t netif::hwaddr_len

number of bytes used in hwaddr

◆ input

err_t(* netif::input) (struct pbuf *p, struct netif *inp)

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

◆ ip_addr

struct ip_addr netif::ip_addr

IP address configuration in network byte order

◆ link_type

u8_t netif::link_type

link type

◆ linkoutput

err_t(* netif::linkoutput) (struct netif *netif, struct pbuf *p)

This function is called by the ARP module when it wants to send a packet on the interface. This function outputs the pbuf as-is on the link medium.

◆ mtu

u16_t netif::mtu

maximum transfer unit (in bytes)

◆ name

char netif::name[2]

descriptive abbreviation

◆ netmask

struct ip_addr netif::netmask

◆ next

struct netif* netif::next

pointer to next in linked list

◆ num

u8_t netif::num

number of this interface

◆ output

err_t(* netif::output) (struct netif *netif, struct pbuf *p, struct ip_addr *ipaddr)

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.

◆ state

void* netif::state

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