The first way is to send 2 wmi command WMI_PDEV_PARAM_TXPOWER_LIMIT2G/WMI_PDEV_PARAM_TXPOWER_LIMIT5G to firmware, the second way is to send WMI_VDEV_SET_TPC_POWER_CMDID to firmware which include more parameters for power control. The first way is disabled in previous patch "ath11k: discard BSS_CHANGED_TXPOWER when EXT_TPC_REG_SUPPORT for 6 GHz". Prepare the parameter for wmi command WMI_VDEV_SET_TPC_POWER_CMDID and send the firmware after vdev start response success from firmware, it is for the second way of power control.
