Bug#928328: Intel I350-NIC shuts down ports after loosing carrier

[Rene 'Renne' Bartsch, B.Sc. Informatics]

echo on > /sys/devices/pci\:00/\:00\:01.0/\:01\:00.0/power/control
echo on > /sys/devices/pci\:00/\:00\:01.0/\:01\:00.1/power/control
echo on > /sys/devices/pci\:00/\:00\:01.0/\:01\:00.2/power/control
echo on > /sys/devices/pci\:00/\:00\:01.0/\:01\:00.3/power/control

solves the problem. This should be "on" by default instead of "auto".

No, i210 and i219 detect the carrier correctly even when un-plugging and 
plugging back the cable.
Only the i350 fails to reconnect.

Are other Intel NICs affected by this problem as well?

Package: linux-image ???

Module: igb.ko

If there is no device connected or powered off a boot/reboot or a device 
disconnects the port of the i350 powers down
and does not wake up until the next reboot of the machine with the i350. There 
is no activity of the RJ-45 LEDs until reboot.

Disabling EEE does not solve the problem:
