Subject: [net-next-2.6 PATCH 01/23] e1000e: check WoL mode is among set of
	supported modes

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

When setting WoL feature, check the supplied modes are all supported rather
than checking for no support.  This way, if any new modes are added the
driver does not default to not complaining about it if we don't really
support it.
