It is not immediately clear why this is needed. The memory and updating two sets of counters won't come for free, so perhaps a stronger justification than troubleshooting is due? :S Netdev has counters for fallback vs forwarded traffic, so you'd know that traffic hits the SW datapath, plus the rules which are in_hw will most likely not match as of today for flower (assuming correctness). I'm slightly concerned about potential performance impact, would you be able to share some numbers for non-trivial number of flows (100k active?)?
