HardMAC drivers have some special protocol. For example MLME operations the driver only know's the interface. Doing the algorithmn is done by transceiver. The transceiver offers these interface to start such MLME operation. - 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
