Please name these functions with "offload" instead of "flow".
It improves readability because those functions exist for the
purpose of offload.
So i would say:
s/XX_setup_flow_action/XX_setup_offload_action/g
i.e
flow_act_setup becomes offload_act_setup
and things like tcf_gate_flow_act_setup become
tcf_gate_offload_act_setup

Again from a naming convention that tc_setup_flow_action
should be tc_setup_offload_act() really..
Maybe an additional patch for that?

<Rant>
Really - this whole naming of things in flow_offload.{c,h}
is very misleading and simplistic. I know it is not your doing.
The term flow is very much related to exact matches. A better
name would have been "match" (then you dont care if it is
exact, prefix, range, ternary, etc). Note:
In this case you can offload actions independent of matches
so a binding to a match may not even exist.
