    . 关于以太网PAUSE的一点研究

        http://www.latelee.org/programming-under-linux/ethernet-pause-frame-study.html

二、U-Boot设定：

setenv bootargs console=ttymxc0, init=/init video=mxcfb0:dev=ldb,bpp= video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=256M androidboot.console=ttymxc0 consoleblank= androidboot.hardware=freescale cma=384M androidboot.selinux=disabled; saveenv; reset;

三、网络设定：

    . 设定ip：

        ifconfig eth0 10.10.10.10 netmask 255.255.255.0

    . 主板抓包工具：

        tcpdump -i eth0 host 10.10.10.10 &

        tcpdump -vv -i eth0 host 10.10.10.10 &
