struct netif* netif::next [read] |
pointer to next in linked list
struct ip_addr netif::ip_addr [read] |
IP address configuration in network byte order
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.
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.
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.
void(* netif::status_callback)(struct netif *netif) |
This function is called when the netif state is set to up or down
void(* netif::link_callback)(struct netif *netif) |
This function is called when the netif link is set to up or down
void* netif::state |
This field can be set by the device driver and could point to state information for the device.
struct dhcp* netif::dhcp [read] |
the DHCP client state information for this netif
struct autoip* netif::autoip [read] |
the AutoIP client state information for this netif
u8_t netif::hwaddr_len |
number of bytes used in hwaddr
u8_t netif::hwaddr[NETIF_MAX_HWADDR_LEN] |
link level hardware address of this interface
u16_t netif::mtu |
maximum transfer unit (in bytes)
u8_t netif::flags |
flags (see NETIF_FLAG_ above)
char netif::name[2] |
descriptive abbreviation
u8_t netif::num |
number of this interface
u8_t netif::link_type |
link type (from "snmp_ifType" enum from snmp.h)
u32_t netif::link_speed |
(estimate) link speed
u32_t netif::ts |
timestamp at last change made (up/down)
u32_t netif::ifinoctets |
counters
