From: Wey-Yi Guy Date: Fri, 20 Nov 2009 20:04:55 +0000 (-0800) Subject: iwlwifi: set sm_ps_mode as part of cfg parameters X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c15d20c1d19616f73b6fee4befd254d0c37b4d87;p=linux-beck.git iwlwifi: set sm_ps_mode as part of cfg parameters Setting "Spatial multiplexing Power Save" as part of per device configuration parameter. Report to uCode based on priv->conf setting, so driver can have more control of how different devices should operate in power save mode.
