The local maximum transmit power is the maximum power a wireless device allowed to transmit. If Power Constraint is presented, the local maximum power equals to the maximum allowed power defined in regulatory domain minus power constraint. The maximum transmit power is maximum power a wireless device capable of transmitting, and should be used in Power Capability element (7.3.2.16 IEEE802.11 2007). The transmit power from a wireless device should not greater than the local maximum transmit power. The maximum transmit power was not calculated correctly in the current Linux wireless/mac80211 when Power Constraint is presented.

(7.3.2.15 IEEE80211 2007) I have a feeling that looking at the code I understand what you're trying to fix, but please explain it better. johannes ______________________________________________________________________ DSP Group, Inc. automatically scans all emails and attachments using MessageLabs Email Security System. _____________________________________________________________________ ______________________________________________________________________ DSP Group, Inc. automatically scans all emails and attachments using MessageLabs Email Security System. _____________________________________________________________________ -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
