+Each driver script should append the driver to a global DRIVERS variable :
+
+\begin{Verbatim}
+append DRIVERS "driver name"
+\end{Verbatim}
+
+\subparagraph{\texttt{scan\_<driver>}}
+
+This function will parse the \texttt{/etc/config/wireless} and make sure there
+are no configuration incompatibilities, like enabling hidden SSIDS with ad-hoc mode
+for instance. This can be more complex if your driver supports a lof of configuration
+options. It does not change the state of the interface.
+
+Example:
+\begin{Verbatim}
+scan_dummy() {
+ local device="$1"
+
+ config_get vifs "$device" vifs
+ for vif in $vifs; do
+ # check config consistency for wifi-iface sections
+ done
+ # check mode combination
+}
+\end{Verbatim}
+
+\subparagraph{\texttt{enable\_<driver>}}
+
+This function will bring up the wifi device and optionally create application specific
+configuration files, e.g. for the WPA authenticator or supplicant.
+
+Example:
+\begin{Verbatim}
+enable_dummy() {
+ local device="$1"
+
+ config_get vifs "$device" vifs
+ for vif in $vifs; do
+ # bring up virtual interface belonging to
+ # the wifi-device "$device"
+ done
+}
+\end{Verbatim}
+
+\subparagraph{\texttt{disable\_<driver>}}
+
+This function will bring down the wifi device and all its virtual interfaces (if supported).
+
+Example:
+\begin{Verbatim}
+disable_dummy() {
+ local device="$1"
+
+ # bring down virtual interfaces belonging to
+ # "$device" regardless of whether they are
+ # configured or not. Don't rely on the vifs
+ # variable at this point
+}
+\end{Verbatim}
+
+\subparagraph{\texttt{detect\_<driver>}}
+
+This function looks for interfaces that are usable with the driver. Template config sections
+for new devices should be written to stdout. Must check for already existing config sections
+belonging to the interfaces before creating new templates.
