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

Field Documentation

◆ flags

u8_t netif::flags

flags (

See also: Flags)

◆ hwaddr

u8_t netif::hwaddr[6U]

link level hardware address of this interface

◆ hwaddr_len

u8_t netif::hwaddr_len

number of bytes used in hwaddr

◆ igmp_mac_filter

netif_igmp_mac_filter_fn netif::igmp_mac_filter

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

◆ input

netif_input_fn netif::input

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

◆ ip6_addr

ip_addr_t netif::ip6_addr[3]

Array of IPv6 addresses for this netif.

◆ ip6_addr_state

u8_t netif::ip6_addr_state[3]

The state of each IPv6 address (Tentative, Preferred, etc).

See also: ip6_addr.h

◆ ip6_addr_valid_life

u32_t netif::ip6_addr_valid_life[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_autoconfig_enabled

u8_t netif::ip6_autoconfig_enabled

is this netif enabled for IPv6 autoconfiguration

◆ ip_addr

ip_addr_t netif::ip_addr

IP address configuration in network byte order

◆ link_callback

netif_status_callback_fn netif::link_callback

This function is called when the netif link is set to up or down

◆ link_speed

u32_t netif::link_speed

(estimate) link speed

◆ link_type

u8_t netif::link_type

link type (from "snmp_ifType" enum from snmp_mib2.h)

◆ linkoutput

netif_linkoutput_fn netif::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.

◆ mib2_counters

struct stats_mib2_netif_ctrs netif::mib2_counters

counters

◆ mld_mac_filter

netif_mld_mac_filter_fn netif::mld_mac_filter

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

◆ mtu

u16_t netif::mtu

maximum transfer unit (in bytes)

◆ mtu6

u16_t netif::mtu6

maximum transfer unit (in bytes), updated by RA

◆ name

char netif::name[2]

descriptive abbreviation

◆ next

struct netif* netif::next

pointer to next in linked list

◆ num

u8_t netif::num

number of this interface. Used for Interface Identification API and NETIF related, as well as for IPv6 zones

◆ output

netif_output_fn netif::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()

◆ output_ip6

netif_output_ip6_fn netif::output_ip6

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()

◆ remove_callback

netif_status_callback_fn netif::remove_callback

This function is called when the netif has been removed

◆ rs_count

u8_t netif::rs_count

Number of Router Solicitation messages that remain to be sent.

◆ state

void* netif::state

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

◆ status_callback

netif_status_callback_fn netif::status_callback

This function is called when the netif state is set to up or down

◆ ts

u32_t netif::ts

timestamp at last change made (up/down)
