[Hardy] Support Intel 82574L gigabit ethernet cards

[Stefan Bader]

SRU Justification:

Impact: The e1000e driver shipped with Hardy does not support the 82574L cards found on some newer server boards. This prevents any network connection for those.

Fix: Pick the latest standalone driver from Intel and replace the current e1000e code in the backports modules package with that.

Testcase: Using the new backports driver network card(s) are detected and working. Before that no network card was detected.

This bug was fixed in the package linux-backports-modules-2.6.24 - 2.6.24-30.42

Just for guys who may arrive here after searching:
1.there's kernel bug in intel 82574L e1000e driver on centos 6(MSI/MSI-X interrupts issue), we can resolve this by install kmod-e1000e package from ELrepo.org and later add pcie_aspm=off e1000e.IntMode=1,1 e1000e.InterruptThrottleRate=10000,10000 acpi=off to kernel parameters.

2.For the high Tx traffic, this was caused by port 53 dns flooding attack. I've resolved this by writing some iptable rules. More info here: [URL="http://www.doxer.org/learn-linux/resolved-port-53-dns-flooding-attack/"]port 53 dns flooding attack[/URL]
