From d21b31fd53626f9c1d14fc676793dbe86b44d1c6 Mon Sep 17 00:00:00 2001 From: Luis Carlos Cobo Date: Thu, 2 Aug 2007 13:16:02 -0400 Subject: [PATCH] libertas: keep mesh autostart enabled while asleep After loading the firmware, mesh autostart will be disabled. After that, the user will still be able to enable or disable it at will. On suspend, it will be always activated and later on resume it will go back to the state it had before going to sleep.
