From ae63a33ec9b598b3454cf0d29077fa17b616c42a Mon Sep 17 00:00:00 2001 From: Deepak Saxena Date: Sun, 31 Oct 2010 13:40:33 +0000 Subject: libertas: EHS_REMOVE_WAKEUP is not always supported Certain firmware versions, particularly the 8388 found on the XO-1, do not support the EHS_REMOVE_WAKEUP command that is used to disable WOL. Sending this command to the card will return a failure that would get propagated up the stack and cause suspend to fail. Instead, fall back to an all-zero wakeup mask.
