Sorry, where would it record that? I can't find any stats counters on the "match" either in the software path or the offload API. > the "vlan action" would record x bytes. > the "redirect" would record size x+vlaninfo bytes > the egress of eth0 would recorr x+vlaninfo bytes Am I right in thinking that offloaded counters don't do that? As far as I can tell, the drivers with flower offload all use tcf_exts_stats_update() which takes a single 'bytes' count and adds it to all the actions. (Presumably this is pre-edit length.) -Ed
