From c9936e44f19870fcea6835e127a4181005ef06ae Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Wed, 8 May 2013 15:37:19 -0400 Subject: [PATCH] mwifiex: fix setting of multicast filter commit ccd384b10420ac81ba3fb9b0a7d18272c7173552 upstream. A small bug in this code was causing the ALLMULTI filter to be set when in fact we were just wanting to program a selective multicast list to the hardware. Fix that bug and remove a redundant if condition in the code that follows. This fixes wakeup behaviour when multicast WOL is enabled. Previously, all multicast packets would wake up the system. Now, only those that the host intended to receive trigger wakeups. Signed-off-by: Daniel Drake Acked-by: Bing Zhao Signed-off-by: John W.
