I think Bruce was talking about a working distribution (the one you used to
build LFS for example). Boot it and run lsmod.
The information you get there could indicate the right driver for the kernel.

Before that and if you are still on LFS:
ip link list

If you see only lo and sit0, it means you do not have the good device driver
in the kernel. If you see something like enp0s2, it means something is wrong
with the udev files, but at least you can try to bring that interface up.

Also, I see:
 Adding IPv4 address to the eth0 interface

Are you sure you want Usually, the .1 address is that of the
ethernet hub which connects your local network to the outside world. I'd try (unless you have many computers on your local network, that address
should be free...)
