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! :)

Alexander
