Just curious, any specific reason why to choose the ELrepo module over the one coming with the CentOS kernel?
I have an RHEL 6 system with an "Intel Corporation 82574L Gigabit Network Connection" NIC, where the e1000e module of the RHEL kernel fails to drive the hardware (no traffic possible, strange effects when tcpduming it). With the kmod-e1000e from ELrepo the 2 onboard 82574L NICs now work.
You may want to look through this ELRepo web site:
http://elrepo.org/tiki/Driver+Versions
As for the e1000e driver, the version offered by ELRepo is newer than what is in the EL6 kernel. Often times, ELRepo drivers are built from the manufacturer's source files, which would not happen with the upstream kernels because their source is from kernel.org).
But if you'd like more info or questions regarding ELRepo's drivers, you will need to ask on the ELRepo mailing list.

Thanks Akemi for your response.
I know you are part of the ELrepo team and saw you contributing to a bugzilla ticket, asking for updating the e1000e kernel module with recent Intel sources. I understand the point the Red Hat team is making, when they say, they will only update when the Intel version found their way into Linus's vanilla kernel tree.
Though I am planning to open an upstream ticket because the 2 Intel 82574L NICs are not usable with plain RHEL 6, but they are using the ELrepo module. Unfortunately I was not able to trace and dump much useful information to fill in the ticket besides to note that simply no network traffic is going through the NICs with the RHEL 6 kernel module.
Sidenote: The e1000e module coming with CentOS 5.5 does drive the Intel 82574L chips correctly on another box. The boards are btw. a Supermicro X8SIL.
Glad there is the ELrepo! :)
