ETHERNET
一 功能简介
以太网控制器也称以太网适配器，就是我们通常称的“网卡”，x2600E 以太网接口,只有一个phy_clk。支持百兆rmii。
二 驱动配置
选择主配置文件：x2600e_vast_v20_nand_5.10_factory_defconfig
进入iconfig配置以太网驱动
三 基础验证
3.1 查看网络设备节点
# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 //以太网设备节点一般是ethX命名的

3.2 配置ip地址及子网掩码
配置格式为
ifconfig [⽹络设备] [ip地址] netmask [⼦⽹掩码] up
# ifconfig eth0 10.4.3.202 netmask 255.255.255.0 up
# [ 638.103441] eth0: device MAC address 4a:9e:6d:a6:60:79
# [ 640.100211] stmmaceth stmmaceth.0 eth0: Link is Up - 100Mbps/Full - flow control off
# ifconfig //查看网络配置是否生效
eth0 Link encap:Ethernet HWaddr 12:7F:5B:25:4C:4C

3.3 配置网关地址
配置格式为
route add default gw [⽹关]
# route add default gw 10.4.3.1
3.4 ping 百度测试
开发板已经默认添加了域名解析，可以不用自己添加
# cat /tmp/resolv.conf
nameserver 202.96.134.133 # wlan0
nameserver 8.8.8.8 # wlan0
# ping www.baidu.com

四 mac phy 寄存器调试
cmd_mdio
read operation: cmd_mdio eth reg_addr
write operation: cmd_mdio eth addr value
For example:
cmd_mdio eth0 1 读mac_phy寄存器
cmd_mdio eth0 0 0x12 写mac_phy寄存器
