There have been a lot of bug fixes since then. I would suggest updating
to a new kernel, but if thats not an option you might try the
out-of-tree driver available from
https://sourceforge.net/projects/e1000/files/e1000e%20historic%20archive/
We no longer provide active support or releases for these since we have
moved to only supporting the upstream driver for this product. However,
that decision was made long after the life of Fedora Core 25, so the
latest version here might work for you. No guarantee.
Your best bet is to update your kernel.
Thanks,
Jake
