Makes sense, thanks for the extra information. I think it would be worth adding all of this to the commit message! Regarding the patch - you are only adding flow types, not a new field (which are defined as RXH_*). If we want to hash on an extra field, I think we need to specify that field as well? > Thank you for your understanding. > --- > Sorry!
