Well, arguably, you can just do that unconditionally. If you want to do it "right" according to the nl80211 API that we introduced due to wext compatibility (IIRC), you'd have to look at the value passed in enum nl80211_tx_power_setting. This can take NL80211_TX_POWER_AUTOMATIC - no limit from userspace NL80211_TX_POWER_LIMITED - limit, but allow using less than specified NL80211_TX_POWER_FIXED - use exactly what userspace wanted I don't think any driver really implements this today, but you could take this as a hint and only enable TPC (with or without the user's specified limit) in the first two cases. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
