I'll get that onto buildlogs for testing while I am working on the CentOS Linux 7 upgrade builds. And yes, people do need to understand that Red Hat backports newer firmware and drivers to the older kernels. There are plenty of 4.x kernel things backported. So, as you correctly pointed out, you can't treat the Red Hat 3.10.x kernels like kernel.org 3.10.x kernels. <snip>
