Yes, that table has a maximum value of 8, and the table will actually remain that way, but EHT introduced a way to encode more levels for 320 MHz channels. Remove IEEE80211_MAX_NUM_PWR_LEVEL and, for ath11k being the only user, add ATH11K_NUM_PWR_LEVELS, where it makes sense since it cannot support 320 MHz channels.
