-/*
- * The alternate user space API to configure all those Wireless Extensions
- * is through RtNetlink.
- * This API support only the new driver API (iw_handler).
- *
- * This RtNetlink API use the same query/reply model as the ioctl API.
- * Maximum effort has been done to fit in the RtNetlink model, and
- * we support both RtNetlink Set and RtNelink Get operations.
- * On the other hand, we don't offer Dump operations because of the
- * following reasons :
- *	o Large number of parameters, most optional
- *	o Large size of some parameters (> 100 bytes)
- *	o Each parameters need to be extracted from hardware
- *	o Scan requests can take seconds and disable network activity.
- * Because of this high cost/overhead, we want to return only the
- * parameters the user application is really interested in.
- * We could offer partial Dump using the IW_DESCR_FLAG_DUMP flag.
- *
- * The API uses the standard RtNetlink socket. When the RtNetlink code
- * find a IFLA_WIRELESS field in a RtNetlink SET_LINK request,
- * it calls here.
