FWIW my whole reason for suggesting DONT_CARE==0 in the first place
was so that drivers could just use it as a boolean, e.g.
if (act->hw_stats && !(act->hw_stats & FLOW_ACTION_HW_STATS_BLAH))
error("driver only supports BLAH stats");
If you're not even doing that then the case for DONT_CARE == ~0 is
even stronger.
Sorry I wasn't quick enough on the draw to say this before v4 was
applied (I was waiting for an answer on the v2 thread; posting a
Nack on v3 felt like it might come across as needlessly combative).
