If I don't bind it to a protocol, it ends up in ptype_all, if I do, it ends up in &ptype_base. ptype_all is processed before the rx_handler, ptype_base is processed after the rx handler. Hooking into ptype_all wastes tons of CPU cycles, hooking into ptype_base does not solve the problem. - Felix -- 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
