I'm now leaning towards the
approach of adding "unsigned long cookie" to struct flow_action_entry

For concreteness, here's what that looks like: patch 1 is replaced with
the following, the other two are unchanged.
Drivers now have an easier job, as they can just use the cookie directly
as a hashtable key, rather than worrying about which action types share
indices.
Per my other email, this will break tc semantics. It doesnt look
possible to specify an index from user space. Did i miss
something?
