【AT-START-F407测评】ETH + LwIP2.1.2 iPerf 实测63.6MB/s
刚刚用BSP自带的DEMO ETH实测了一下网口加载和速度, 63.6MB/s。只改了IP地址：

Adds your network interface to the netif_list. Allocate a struct
netif and pass a pointer to this structure as the first argument.
Give pointers to cleared ip_addr structures when using DHCP,

your ethernet netif interface. The following code illustrates it's use.*/
