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 netif::flags |
flags (
u8_t netif::hwaddr[6U] |
link level hardware address of this interface
u8_t netif::hwaddr_len |
number of bytes used in hwaddr
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.
netif_input_fn netif::input |
This function is called by the network device driver to pass a packet up the TCP/IP stack.
ip_addr_t netif::ip6_addr[3] |
Array of IPv6 addresses for this netif.
u8_t netif::ip6_addr_state[3] |
The state of each IPv6 address (Tentative, Preferred, etc).
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.
u8_t netif::ip6_autoconfig_enabled |
is this netif enabled for IPv6 autoconfiguration
ip_addr_t netif::ip_addr |
IP address configuration in network byte order
netif_status_callback_fn netif::link_callback |
This function is called when the netif link is set to up or down
u32_t netif::link_speed |
(estimate) link speed
u8_t netif::link_type |
link type (from "snmp_ifType" enum from snmp_mib2.h)
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.
struct stats_mib2_netif_ctrs netif::mib2_counters |
counters
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.
u16_t netif::mtu |
maximum transfer unit (in bytes)
u16_t netif::mtu6 |
maximum transfer unit (in bytes), updated by RA
char netif::name[2] |
descriptive abbreviation
struct netif* netif::next |
pointer to next in linked list
u8_t netif::num |
number of this interface. Used for Interface Identification API and NETIF related, as well as for IPv6 zones
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()
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()
netif_status_callback_fn netif::remove_callback |
This function is called when the netif has been removed
u8_t netif::rs_count |
Number of Router Solicitation messages that remain to be sent.
void* netif::state |
This field can be set by the device driver and could point to state information for the device.
netif_status_callback_fn netif::status_callback |
This function is called when the netif state is set to up or down
u32_t netif::ts |
timestamp at last change made (up/down)
