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
| u8_t netif::flags |
flags (see NETIF_FLAG_ above) 该接口状态、属性字段
| ip_addr_t netif::gw |
| u8_t netif::hwaddr[6U] |
link level hardware address of this interface 该接口物理地址
| u8_t netif::hwaddr_len |
number of bytes used in hwaddr该接口物理地址长度
| netif_input_fn netif::input |
This function is called by the network device driver to pass a packet up the TCP/IP stack. 向IP层输入数据包
| ip_addr_t netif::ip_addr |
IP address configuration in network byte order
| netif_linkoutput_fn netif::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. 底层数据包发送
| u16_t netif::mtu |
maximum transfer unit (in bytes) 该接口允许的最大数据包长度，多是1500
| char netif::name[2] |
descriptive abbreviation 该接口的名字
| ip_addr_t netif::netmask |
| struct netif* netif::next |
pointer to next in linked list
| u8_t netif::num |
number of this interface 该接口的编号
| netif_output_fn netif::output |
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. 发送IP数据包
| void* netif::state |
This field can be set by the device driver and could point to state information for the device. 自由设置字段，比如指向底层设备相关信息
