In our case, it was the driver. Google e1000e-1.6.2.tar.gz

Hi all,
I'm facing a serious problem with the e100e kernel module for Intel 82574L gigabit nics on Centos 6.
I have also had problems with an Intel Gbit nic in a Dell Optiplex 760 using the e1000 module. If it would come up it would come up at 100Mbit speed. Only unplugging the LAN cable en reinserting it in the switch would sometimes result in the proper 1Gb speed. After replacing the 3Com Gbit switch with a DLink Gbit switch things started to work ok.
As suggested, you could try out the e1000 kernel module form elrepo (if it works, good for you) but you may want to look into the switch too.
Hmmm, we had a problem like that, but in our case, it was the NIC. If someone's already asked this - I didn't read the list over the weekend - ignore the request, but if not, while it's not working, what's the o/p of ethtool eth<whatever>
