Field Documentation

u8_t flags

flags (see NETIF_FLAG_ above)

Definition at line 269 of file netif.h.

u8_t hwaddr[NETIF_MAX_HWADDR_LEN]

link level hardware address of this interface

Definition at line 267 of file netif.h.

u8_t hwaddr_len

number of bytes used in hwaddr

Definition at line 265 of file netif.h.

netif_input_fn input

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

Definition at line 201 of file netif.h.

netif_linkoutput_fn linkoutput

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.

Definition at line 211 of file netif.h.

u16_t mtu

maximum transfer unit (in bytes)

Definition at line 263 of file netif.h.

char name[2]

descriptive abbreviation

Definition at line 271 of file netif.h.

struct netif* next

pointer to next in linked list

Definition at line 184 of file netif.h.

u8_t num

number of this interface

Definition at line 273 of file netif.h.

void* state

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

Definition at line 234 of file netif.h.
