Intel Pro/100 network card on RedHat/CentOS

If you are wondering how to make this very old network card to work under new RedHat7 or CentOS7 what you need is just this RPM: kmod-e100.
Make sure you have the correct kernel. At the time I am writing this kmod-e100-3.5.24-2.el7_4.elrepo.x86_64.rpm is compatible with kernel-3.10.0-693.2.2.el7.x86_64.rpm.
