Bring up a working system and run lsmod. We have no way to tell what
hardware you have, but we do refer to several references on configuring
a kernel in Section 8.3.
You can also just build all ethernet drivers as modules. You may get
some interface like enp2s0. See
The objective of udev-lfs-208-1/init-net-rules.sh in Section 6.62 is to
create a udev rule to rename this back to eth0.
