Well that's fine... tcpdump for example does IFF_PROMISC while it runs so nobody who doesn't care will notice the difference, but I guess you get the power saving while IFF_PROMISC is off and the Monitor mode interface is up. But anyone who tcpdumps on a Monitor mode interface still always sees the whole picture, not the synthesized one. Sounds like a good general way to me. -Andy - 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
