Rather than me trying to whack-a-mole all the places in netfilter that create actions... given that the other user is TC, which explicitly sets hw_stats, maybe I should instead make flow_rule_alloc() populate all the hw_stats with DONT_CARE? It certainly makes for a shorter patch, and makes it less likely that bugs will be introduced later when new action offloads get added to netfilter by forgetting to set hw_stats. And it means the patch doesn't rely on me knowing things about netfilter internals which I apparently don't.
