You need an updated version of kmod-forcedeth for your ethernet card. I'm guessing you downloaded the old one manually and installed it when you should also have downloaded and installed the elrepo-release package at the same time. With the elrepo-release package installed, yum knows about the ELRepo repo and will update to newer packages as they are made available. Kmod packages often require rebuilding when a new point release (like 7.4) comes out as RH change the kernel ABI.
