This happens through a number of hardware capability structs - * described below. - * - * The fundamental structure for each device is the 'wiphy', of which each - * instance describes a physical wireless device connected to the system. Each - * such wiphy can have zero, one, or many virtual interfaces associated with - * it, which need to be identified as such by pointing the network interface's - * @ieee80211_ptr pointer to a &struct wireless_dev which further describes - * the wireless part of the interface, normally this struct is embedded in the - * network interface's private data area. Drivers can optionally allow creating - * or destroying virtual interfaces on the fly, but without at least one or the - * ability to create some the wireless device isn't useful. - * - * Each wiphy structure contains device capability information, and also has - * a pointer to the various operations the driver offers.
