+Subject: [B.A.T.M.A.N.] [PATCH openwrt-feed only] batman-adv: fix metadata stripping
+
+a new optimisation in openwrt is stripping some metadata information, invluding
+the module version which is used by batctl to tell the user which version
+batman-adv the node is currently running.
+
+Un-define this constant to prevent the metadata from being stripped
