This doesn't compile, I'd expect to see hunks such as:

@@ -184,7 +184,7 @@ void *dst_alloc(struct dst_ops *ops, struct net_device *dev,
 	dst->xfrm = NULL;
 #endif
 	dst->input = dst_discard;
-	dst->output = dst_discard;
+	dst->output = dst_discard_sk;
 	dst->error = 0;
 	dst->obsolete = initial_obsolete;
 	dst->header_len = 0;

for this file, but I don't.  Maybe you posted an outdated revision of your
patch?  There also aren't the necessary decnet and XFRM changes, layers
which also use dst->output().

Anyways, I'm splitting up your patches and sorting this out.
