FW starts using legacy power table command (0x77) for device wide power settings. Currently this command contains only option flags field. It can configure the following: CAM (Continuous Active Mode) and POWER_SAVE_ENABLE debug option. Send this command when firmware is loaded - D0 and D3. Note: Setting this command is important to avoid unwanted FW behavior. It particularly fixes a bug when a device does not drop to low power after disassociation from AP.
