◆ hwaddr

u8_t netif::hwaddr[6U]

link level hardware address of this interface

Definition at line 311 of file netif.h.

◆ hwaddr_len

u8_t netif::hwaddr_len

number of bytes used in hwaddr

Definition at line 309 of file netif.h.

◆ input

netif_input_fn netif::input

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

Definition at line 252 of file netif.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.

◆ mtu

u16_t netif::mtu

maximum transfer unit (in bytes)

Definition at line 307 of file netif.h.

◆ 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

Definition at line 317 of file netif.h.

Referenced by netif_add(), and netif_find().

◆ state

void* netif::state

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