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:

Sorry it took so long to get back to you. This is a high volume list of commits and you really should be using e1000-devel at sourceforge.net or linux-nics at intel.com for questions.
What are you trying to do? There's a good chance the PME bits are overridden by the NVM. Please check the i210 data sheet for more information. You should be able to find it on the intel.com web site and the easiest way to find it is to use google.

Sorry about that. It's because [1] lists here for "in-kernel support".
If it's not the best place for that, probably the page should be
updated...

What I tried to do is to make i210 (igb) responses to ethernet cable
plug event when it's runtime suspended, i.e. igb_runtime_resume() not
being called.
Can you provide more information on when the NVM overrides the PME
bits, and how to disable this behavior? Also, the sheet mentioned a
"flash-less" mode - how do I enable it?
