Talked with one of the TC maintainers today... I think it would be nice to have a TC action where you can set a transmit power per classifier... not sure there exists many way how to handle it. Also there was an idea according to 6lowpan to handle it per ndisc entry. :-/ If you really want to set it per frame. 802.11 people might be interessted in the "wireless tx power TC action" as well... - Alex -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
