+Subject: batctl: Return EXIT_FAILURE when throughputmeter failed
+
+The command returned a success even an error was shown during the
+execution.
+
+  $ (sudo batctl tp 77:77:77:77:77:77 && echo true) || echo false
+  Destination unreachable
+  true
+
+Instead it should indicate a failure when the kernel replied with a
+non-success return_value:
+
+  $ (sudo ./batctl tp 77:77:77:77:77:77 && echo true) || echo false
+  Destination unreachable
+  false
