I meant changing ->act() to have the same prototype as tcf_act_exec()
itself:

-       int     (*act)(struct sk_buff **, struct tc_action *);
+       int     (*act)(struct sk_buff **, struct tc_action *, struct 
tcf_result *);

Since its already reset after actions are executed, we only need to
additionally reset it for packets that take a different path.
At the moment I think this only happens with mirred.
