Hi, Thank you!
I'm studying the source code, but I'm getting a bit lost... In ofproto-dpif.c there are stat_update functions and some comments pointing to dpif_flow_get(), but I can't seem to find how the stats are exactly transferred between datapath and the corresponding (sub)facets in userspace or where this update interval is defined. Can you give me a clue?
