Subject: [net-next PATCH 2/7] e1000e: do not attempt to disable smart
	powerdown if not supported

From: Bruce Allan <bruce.w.allan@...el.com>

During reset, the driver was attempting to disable the Smart Powerdown
feature even if the part does not support Smart Powerdown.  Check for
support before attempting to disable the feature.
