Description: 其中的源地址和目的地址是指网卡的硬件地址（也叫MAC地址），长度是48位，是在网卡出厂时固化的。可在shell中使用ifconfig命令查看，“HWaddr 00:15:F2:14:9E:3F”部分就是硬件地址。协议字段有三种值，分别对应IP、ARP、RARP。帧尾是CRC校验码。(The source address and destination address refer to the hardware address of the network card (also known as the MAC address), and the length is 48 bits, which is cured when the network card is factory. You can use the ifconfig command in shell to see that the "HWaddr 00:15:F2:14:9E:3F" section is the hardware address. The protocol field has three values, corresponding to IP, ARP, and RARP. The frame tail is the CRC checksum.)

Description: ZigBee协议适应无线传感器的低花费、低能量、高容错性等的要求。Zigbee的基础是IEEE 802.15.4。但IEEE仅处理低级MAC层和物理层协议，因此Zigbee联盟扩展了IEEE，对其网络层协议和API进行了标准化。Zigbee是一种新兴的短距离、低速率的无线网络技术。主要用于近距离无线连接。它有自己的协议标准，在数千个微小的传感器之间相互协调实现通信。(The ZigBee protocol adapts to the requirements of low cost, low energy and high fault tolerance of wireless sensor. The basis of Zigbee is IEEE 802.15.4. But IEEE only handles low-level MAC layer and physical layer protocols, so the Zigbee alliance extends IEEE, standardization of its network layer protocol and API. Zigbee is a new wireless network technology with short distance and low rate. It is mainly used for close range wireless connection. It has its own protocol standard, which coordinates communication between thousands of tiny sensors.)

Description: ERPS协议
快速以太网是通过控制MAC地址老化来保证拓扑变化时数据报文可以快速的发送到正确的链路上。一般情况MAC老化时间300秒，环网协议可以控制MAC地址表急速老化，默认小于50毫秒。(ERPS protocol
Fast Ethernet ensures that data messages can be sent to the correct link quickly when the topology changes by controlling MAC address aging. Generally speaking, the MAC aging time is 300 seconds. The ring protocol can control the rapid aging of the MAC address table. The default time is less than 50 milliseconds.)

Description: The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that provides
easier Internet connection to embedded systems. W5500 enables users to have the
Internet connectivity in their applications just by using the single chip in which TCP/IP
stack, 10/100 Ethernet MAC and PHY embedded.
WIZnet‘s Hardwired TCP/IP is the market-proven technology that supports TCP, UDP,
IPv4, ICMP, ARP, IGMP, and PPPoE protocols. W5500 embeds the 32Kbyte internal
memory buffer for the Ethernet packet processing. If you use W5500, you can
implement the Ethernet application just by adding the simple socket program. It’s
faster and easier way rather than using any other Embedded Ethernet solution. Users
can use 8 independent hardware sockets simultaneously.
SPI (Serial Peripheral Interface) is provided for easy integration with the external
MCU. The W5500’s SPI supports 80 MHz speed and new efficient SPI protocol for the
high speed network communication. In order to reduce power consumption of the
system, W5500 provides WOL (Wake on LAN) and power down mode.
