| netif_input_fn | input |
| This function is called by the network device driver to pass a packet up the TCP/IP stack. | |
| netif_output_fn | output |
| This function is called by the IP module when it wants to send a packet on the interface. | |
| netif_linkoutput_fn | linkoutput |
| This function is called by ethernet_output() when it wants to send a packet on the interface. | |

Detailed Description
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

Field Documentation
| u8_t hwaddr[NETIF_MAX_HWADDR_LEN] |
| u8_t hwaddr_len |
| u8_t ip6_addr_state[LWIP_IPV6_NUM_ADDRESSES] |
The state of each IPv6 address (Tentative, Preferred, etc).
- See also:
- ip6_addr.h
| u32_t ip6_addr_valid_life[LWIP_IPV6_NUM_ADDRESSES] |
| u32_t link_speed |
| u8_t link_type |
link type (from "snmp_ifType" enum from snmp_mib2.h)
| void* memory_manager |
Pointer to memory manager.
Definition at line 161 of file ppp_service_if.h.
| u8_t num |
number of this interface.
Used for Interface Identification API and NETIF related, as well as for IPv6 zones
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()
| u8_t rs_count |
| void* service_ptr |
Pointer to PPP Service.
Definition at line 159 of file ppp_service_if.h.
| void * state |
| void* stream |
Pointer to memory stream.
Definition at line 163 of file ppp_service_if.h.
