| Subject: iwlwifi: mvm: disable RX-diversity in powersave |
| |
| From: Johannes Berg <johannes.berg@intel.com> |
| |
| [ Upstream commit e5322b9ab5f63536c41301150b7ce64605ce52cc ] |
| |
| Just like we have default SMPS mode as dynamic in powersave, |
| we should not enable RX-diversity in powersave, to reduce |
| power consumption when connected to a non-MIMO AP. |
