As Bruce stated, this is an igb issue, not e1000e. From your boot.log:

igb: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX
igb: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX

One other piece of info (in addition to what Bruce requested) that would
be useful is after you've done ifconfig eht0 up, cat /proc/interrupts |
grep eth0 and send that output (I want to see your MSI-X configuration).
Cheers,
