iwl3945: disable power save
we see from http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2125 that power saving does not work well on 3945. Since then power saving has also been connected with association problems where an AP deathenticates a 3945 after it is unable to transmit data to it - this happens when 3945 enters power savings mode. Disable power save support until issues are resolved. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> CC: stable@kernel.org Signed-off-by: John W. Linville <linville@tuxdriver.com>
