+Subject: [PATCH] set mcast_rate in mesh mode
+
+The wpa_supplicant code for IBSS allows to set the mcast rate. It is
+recommended to increase this value from 1 or 6 Mbit/s to something higher
+when using a mesh protocol on top which uses the multicast packet loss as
+indicator for the link quality.
+
+This setting was unfortunately not applied for mesh mode. But it would be
+beneficial when wpa_supplicant would behave similar to IBSS mode and set
+this argument during mesh join like authsae already does. At least it is
+helpful for companies/projects which are currently switching to 802.11s
+(without mesh_fwding and with mesh_ttl set to 1) as replacement for IBSS
+because newer drivers seem to support 802.11s but not IBSS anymore.
