Each wireless driver has its own configuration script in \texttt{/lib/wifi/driver\_name.sh} which handles
driver specific options and configurations. This script is also calling driver specific binaries like wlc for
-Broadcom, or hostapd and wpa\_supplicant for atheros.
+Broadcom, or hostapd and wpa\_supplicant for atheros and mac80211.
The reason for using such architecture, is that it abstracts the driver configuration.

\item \texttt{monitor} \\
Monitor mode
+ \item \texttt{mesh} \\
+ Mesh Point mode (802.11s)
+
\item \texttt{wds} \\
WDS point-to-point link
Set the BSSID address to be used for wds to set the mac address of the other wds unit.
\item \texttt{txpower}
- Set the transmission power to be used. The amount is specified in dBm.
+ (Deprecated, set in wifi-device) Set the transmission power to be used. The amount is specified in dBm.
\item \texttt{encryption} \\
Encryption setting. Accepts the following values:
Optional: Isolation is a mode usually set on hotspots that limits the clients to communicate only with the AP and not with other wireless clients.
0 disables ap isolation (default); 1 enables ap isolation.
+ \item \texttt{doth} \\

+\paragraph{Mesh Point}
+
+Mesh Point (802.11s) is only supported by some mac80211 drivers. It requires the iw package
+to be installed to setup mesh links. OpenWrt creates mshN mesh point interfaces. A sample
+configuration looks like this:
+
+\begin{Verbatim}
+config wifi-device "wlan0"
+ option type "mac80211"

\paragraph{Wireless Distribution System}
WDS is a non-standard mode which will be working between two Broadcom devices for instance
OpenWrt supports both 802.1x client and Access Point
configurations. 802.1x client is only working with
-Atheros or mac80211 drivers. Configuration only
-supports EAP types TLS, TTLS or PEAP.
