Referenced by low_level_init(), netif_add(), netif_input(), netif_issue_reports(), netif_remove(), netif_set_down(), netif_set_link_down(), netif_set_link_up(), and netif_set_up().

hwaddr

u8_t netif::hwaddr[NETIF_MAX_HWADDR_LEN]

link level hardware address of this interface

Referenced by low_level_init().

hwaddr_len

u8_t netif::hwaddr_len

number of bytes used in hwaddr

Referenced by low_level_init().

input

netif_input_fn netif::input

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

Referenced by ethernetif_input(), netif_add(), netif_add_noaddr(), slipif_init(), and slipif_rxbyte_input().

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.

Referenced by ethernetif_init().

mtu

u16_t netif::mtu

maximum transfer unit (in bytes)

Referenced by low_level_init(), netif_add(), and slipif_init().

name

char netif::name[2]

descriptive abbreviation

Referenced by ethernetif_init(), netif_add(), netif_find(), netif_index_to_name(), netif_name_to_index(), netif_set_default(), and slipif_init().

next

struct netif* netif::next

pointer to next in linked list

Referenced by netif_add(), and netif_remove().

num

u8_t netif::num

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

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.

Referenced by netif_add(), netif_add_noaddr(), slipif_init(), slipif_output(), slipif_poll(), and slipif_rxbyte().
