It is used to estimate the average retransmissions that will be required to send a nominal frame over a given peer link.

In that case transmission failures will not be taken into account and nodes with that hardware will report a lower (better) link metric than what they should. In other words, those nodes will attract mesh traffic, which will provide a strong incentive for the driver maintainers to set that value correctly :) Cheers, Javier -- Javier Cardona cozybit Inc. -- 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
