+Subject: [PATCH] cfg80211: use only 1Mbps for basic rates in mesh
+
+Mesh used to use the mandatory rates as basic rates, but we got
+the calculation of mandatory rates wrong until some time ago.
+Fix this this broke interoperability with older versions since
+now more basic rates are required, and thus the MBSS isn't the
+same and the network stops working.
+
+Fix this by simply using only 1Mbps as the basic rate in 2.4GHz.
+Since the changed mandatory rates only affected 2.4GHz, this is
+all we need to make it work again.
+
