+.Nm radio
+.Nd interface between low and high level radio drivers
+.Sh DESCRIPTION
+The radio device driver is divided into a high level,
+hardware independent layer, and a low level hardware
+dependent layer.
+The interface between these is the
+.Va radio_hw_if
+structure.
+.Bd -literal
+struct radio_hw_if {
+	int	*open(dev_t, int, int, struct proc *);
+	void	*close(dev_t, int, int, struct proc *);
+	int	*ioctl(dev_t, u_long, caddr_t, int, struct proc *);
+};
+
+.Ed
+.Pp
+
+The high level radio driver attaches to the low level driver
+when the latter calls
+.Va radio_attach_mi .
+This call should be
+.Bd -literal
+    void
+    radio_attach_mi(rhwp, hdlp, dev)
+	struct radio_hw_if *rhwp;
+	void *hdlp;
+	struct device *dev;
+.Ed
+.Pp
+The
+.Va radio_hw_if
+struct is as shown above.
+The
+.Va hdlp
+argument is a handle to some low level data structure.
+It is reserved field for future usage, and actually not used in any 
+low-level driver functions. 
+.Va radio_hw_if
+when the high level driver calls them.
+.Va dev
+is the device struct for the hardware device.
+.Pp
+
+The fields of
+.Va radio_hw_if
+are described in some more detail below.
+
+.Bd -literal
+int open (dev_t dev, int flags, int fmt, struct proc *p);
+  Is called when the radio device is opened.
+  Returns 0 on success, otherwise an error code.
+
+int close (dev_t dev, int flags, int fmt, struct proc *p);
+  Is called when the radio device is closed.
+  Returns 0 on success, otherwise an error code.
+
+int ioctl (dev_t dev, u_long cmd, caddr_t data, int flags, struct proc *p);
+  Is ioctl requests handler function.
+  Returns 0 on success, otherwise an error code.
