I just finished building LFS 10.1 (using Ubuntu 21.04), and the last thing left is to ensure both my network interfaces are working. I have two ethernet ports on my PC, one is a Realtek RTL8125 2.5 GB controller, and the 2nd is a I211 Gigabit Intel controller. Here is the output of " lshw -c network ":
Code:

On my Ubuntu system, the Realtek Controller loads as enp5s0, and the Intel as enp6s0. I have them both configured in /etc/sysconfig/ifconfig.enpXs0 files, as well as the needed /etc/hosts and /etc/resolv.conf files from the LFS book, but when I load my completed operating system, only the Realtek enp5s0 interface shows, and I cannot configure enp6s0. (Interface does not exist error when trying to assign IP Addr).
I tried researching this issue, and have tried compiling all the Intel-Network-Interface Drivers from the Kernel configmenu, as well as downloading and building from drivers directly from source, but neither of these methods has worked. I have also looked at the output for the " dmesg " command, but see no message relating to my Intel interface or firmware that may need to be installed.
If anyone could point me in the right direction of how to fix this issue with my Ethernet Controller, it would be much appreciated. Thanks for your consideration.
I am unsure as to if you have a correct driver but lets assume you put it in correctly.
