Hi Jesse,
We are facing similar issue with interface shutdown over fiber
medium.
We are using 82571EB with e1000e driver and problem is, shutdown not
supported on fiber medium.
Similar shutdown procedure on copper medium, works.
Correct me if I am wrong, I think this chip does not support shutdown on
fiber.
Any plans to support this functionality, in future ? How much time
shutdown support, going to take ?
Regards,
Vishal

Actually I have two ports in a card, and I want to communicate the link
state on both end. I mean, if link of one port is physically down
(cable
unplugged) I can shutdown the other interface. Showing the network
behind second port that they are connected to each other not with me...
If I unload the driver I'll lose control of both port and will not be
able to see if the down port came up or not. So badly in need of this
feature :).
Thanks,
