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

u8_t inet::tcp::netif::hwaddr[NETIF_MAX_HWADDR_LEN]

link level hardware address of this interface

u8_t inet::tcp::netif::hwaddr_len

number of bytes used in hwaddr

err_t(* inet::tcp::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.

Referenced by inet::tcp::TCP_lwIP::TCP_lwIP().

struct ip_addr inet::tcp::netif::ip_addr

IP address configuration in network byte order.

Referenced by inet::tcp::TCP_lwIP::TCP_lwIP().

err_t(* inet::tcp::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.

u16_t inet::tcp::netif::mtu

maximum transfer unit (in bytes)

char inet::tcp::netif::name[2]

descriptive abbreviation

struct netif* inet::tcp::netif::next

pointer to next in linked list

Referenced by inet::tcp::TCP_lwIP::TCP_lwIP().

u8_t inet::tcp::netif::num

number of this interface

Referenced by inet::tcp::TCP_lwIP::TCP_lwIP().

err_t(* inet::tcp::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.

void* inet::tcp::netif::state

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