dex = cmd - SIOCIWFIRSTPRIV;//

if (index < dev->wireless_handlers->num_private)
return dev->wireless_handlers->private[index];//该private命令的handler.
/* Not found */
return NULL;
}


下面wlan_private_args为本wifi网卡驱动的所能支持的所有命令,也就是iwpriv命令所能支持的所有命令

struct iw_handler_def wlan_handler_def = {
num_standard:sizeof(wlan_handler) / sizeof(iw_handler),
num_private:sizeof(wlan_private_handler) / sizeof(iw_handler),
num_private_args:sizeof(wlan_private_args) / sizeof(struct iw_priv_args),
standard:(iw_handler *) wlan_handler,
private:(iw_handler *) wlan_private_handler,
private_args:(struct iw_priv_args *) wlan_private_args,
#if WIRELESS_EXT > 20
get_wireless_stats:wlan_get_wireless_stats,
#endif
};

以下为示意代码,我们的wifi网卡驱动支持如下iwpriv命令.
