Subject: e1000e interface hang on 82574L
Hi folks,
Another networking issue I've run into, this time with e1000e (Intel
Corporation 82574L Gigabit). My new VM cluster appears to drop a NIC -
the port stops responding within Linux and shows the link as being down
with ethtool. My ISP says 'Ports running Half Duplex or reduced speed'
on the port.
When the port stops working I see this in dmesg:

I then don't get an eth2 interface. Only a reboot brings the interface
back. This has happened twice so far on this server in the past week,
both times using v3.2-rc7-3-g4962516.
