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. When firmware support SERVICE_EXT_TPC_REG, it means firmware support the second way for WMI_VDEV_SET_TPC_POWER_CMDID, then ath11k discard BSS_CHANGED_TXPOWER flag from mac80211 which is used to the first way for 6 GHz band in this patch and select the second way in the subsequent patch.
