I'm the one who did the submission. Some of my comments (which I
thought were helpful) have been hidden by Red Hat.

I don't have access, either.

My suggestion for you is to give ELRepo's kmod-e1000e a try. It has
the latest version from Intel (3.1.0.2) as opposed to the version in
the EL kernels (2.3.2-k). There are known cases in which a later
version resolved issues.
