You are talking about the TX key and I am talking about the RX key. We could probably cache the TX key to avoid the key computation on every TX. That's right. But I don't even have it working, yet, so optimization is not my worry, yet. :) But yes, that could be an optimization to be done. -- Greetings Michael. - 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
