Hi,

The device in question uses igb driver, the latest commit from
jkirsher/next-queue.git does not help.
I found a defined but not used variable, E1000_CTRL_EN_PHY_PWR_MGMT,
and add the additional flag to ctrl doesn't help, either.

I can provide more logs if needed.
Below is the output from `lspci -vvv`, PME is suspiciously not enabled:
