Because = I=E2=80=99d basically enable this for all of my flent runs. Preliminarily, I _am_ seeing differences within TCP flows as the = configuration is changed on my OM2P-HS / LEDE setup. There are some = surprises, at least for me, but I=E2=80=99ll save the details until I = post my second round of results because they require a lot of context, = but hopefully these stats help give more insight into what=E2=80=99s = going on. Thanks!=
