mac80211: enable TPC through mac80211 stack
Control per packet Transmit Power Control (TPC) in lower drivers according to TX power settings configured by the user. In particular TPC is enabled if value passed in enum nl80211_tx_power_setting is NL80211_TX_POWER_LIMITED (allow using less than specified from userspace), whereas TPC is disabled if nl80211_tx_power_setting is set to NL80211_TX_POWER_FIXED (use value configured from userspace) Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi83@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
