+ Description
+
+ All DVB frontend devices support the
+FE_GET_INFO ioctl. It is used to identify
+kernel devices compatible with this specification and to obtain
+information about driver and hardware capabilities. The ioctl takes a
+pointer to dvb_frontend_info which is filled by the driver. When the
+driver is not compatible with this specification the ioctl returns an error &return-value-dvb;.
