Subject: iwlwifi: set sm_ps_mode as part of cfg parameters
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c15d20c1d19616f73b6fee4befd254d0c37b4d87;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.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.
