| // A note about the data structure of power management and saving. |
| // |
| // * In each MAC interface (the 'struct iwl_mvm_vif'), there are 2 fields related to this: |
| // |
| // - pm_enabled: indicates whether the power management is allowed on this interface. |
| // It is only enabled in some condition (e.g. only one mode is active). |
| // See iwl_mvm_power_set_pm() for details. |
| // |
| // - ps_disabled: indicates that this interface requires power saving to be disabled. |
| // |
| // * For an MVM (the 'struct iwl_mvm'), there is also a field called 'ps_disable' to |
| // indicate if the power save is allowed. It is obvious that this field aggregates |
| // the 'ps_disabled' of all interfaces. If any of interface PS is disabled, the MVM PS |
| // is disabled as well. |
