keystone2-k2e 在u-boot下2个网卡都能使用。进到Linux只能使用其中一个网卡,
通过这个设置 setenv args_all 'setenv bootargs console=ttyS0,115200n8 rootwait=1 ip=${ipaddr}::${gatewayip}:${netmask}::eth1:off'
setenv args_all 'setenv bootargs console=ttyS0,115200n8 rootwait=1 ip=${ipaddr}::${gatewayip}:${netmask}::eth0:off'
可以控制Linux那个口能用,但是不能同时使用。
不能用的网卡插拔网线,会识别到,就是不能ping 通. 能ping通的网卡,能ping设置的2个Ip地址,mac是同一个

怎么设置能是2个网卡都能使用?
