How to enable eth1 get IP automatically when kernel startup?

[liuyonggang]

Environment: Yocto

Platform: Imx8qxp

OS: Linux

Version: 4.14.98

There are two Ethernets (eth0&eth1) on my board.I have forbidden busybox first.eth0 can gets IP automatically when kernel startup.But eth1 cann't gets IP automatically when kernel startup.secondly,I have masked "obj-$(CONFIG_IP_PNP) += ipconfig.o" . But eth0 still can gets IP automatically when kernel startup.

I can't find config IP corresponding code.Can someone tell me which file?

this document is about that  RMII PHY is NXP TJA1101, it output 50MHz REF_CLK to i.MX8QXP. what's your design? you use your own board or just imx8qxp board with base board? how about your dual ethernet?

Hi Xie，

   My board is ES1.The two RGMII PHY chips are Marvell_88Q2110。I have already find where can enable eth0&eth1 to get IP

automatically.It in systemd/systemd/50-wired.network file.The content of the file is as followings:

[Match]
Name=eth0

[Network]
DHCP=ipv4

and I modify "Name=eth0" to "Name=eth*" .It can be okay.

Thanks all the same.
