+\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.
+
 \paragraph{Wireless Distribution System}
 
 WDS is a non-standard mode which will be working between two Broadcom devices for instance
