66AK2H14 如何是4个千兆网同时使用

从负数开始

自己板子，4个千兆网,没有使用PHY，使用MAC to MAC FORCELINK

eth0,eth1在linux下能够正常使用

但是eth2,eth3在linux不能ping PC，uboot 能够eth2 eth3能够ping通PC

linux 使用的命令：

ifconfig eth2 192.169.1.3 up

root@k2hk-evm:~# ifconfig
eth0      Link encap:Ethernet  HWaddr 7C:66:9D:CE:AD:8A
          inet addr:10.0.0.122  Bcast:10.0.0.255  Mask:255.255.255.0
          inet6 addr: fe80::7c66:9d00:1ce:ad8a/64 Scope:Link

eth2      Link encap:Ethernet  HWaddr AE:2E:9E:C7:1E:00
          inet addr:192.168.1.3  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:61 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0
          RX bytes:6236 (6.0 KiB)  TX bytes:6236 (6.0 KiB)

请问：如果需要使能eth2,eth3,在linux 使用ifconfig;是否还需要在linux内核或者设备树进行修改?
