LS1028A网络问题-YT8614+YT8521

按照V2.3的底板单独做的底板，现在系统可以正常启动，但是网络设备找不到，不知道什么原因。麻烦大侠给看看！
1、执行ifconfig后，只显示eno2和lo
eno2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1532
        inet6 fe80::744b:a4ff:fe8d:3032  prefixlen 64  scopeid 0x20<link>
        ether 76:4b:a4:8d:30:32  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 21  bytes 2448 (2.4 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 635  bytes 343897 (343.8 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 635  bytes 343897 (343.8 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

2、按照手册，对eno0执行操作
root@forlinx:~# sudo ifconfig eth0 192.168.1.3
SIOCSIFADDR: No such device
eth0: ERROR while getting inte**ce flags: No such device
root@forlinx:~# I2fwd -c 0xf -n 1 -- -p 0xc -q 1 --no-mac-uodating
-bash: I2fwd: command not found
root@forlinx:~# cat /etc/network/inte**ces.d/eno0
auto eno0
iface eno0 inet static

root@forlinx:~# ip addr flush dev eno0
root@forlinx:~# systemctl restart networking.service

3、根据1和2的打印信息，eno0的phy没有正常工作，我检查电路后，我的底板与v2.3的开发板硬件配置一样，无法确定是哪里出问题

PHY的解复位信号正常吗？{:2_39:}
