It works here too. I see far more ECN marks & drops on my egress than
ingress; gigabit to 10mbit is quite a transition that needs to be
managed. 40mbit to gigabit ingress is less of a problem *and* my ISP
(and BT's infrastructure over which it runs) has a rate limiter to help
prevent overfilling the link. As an experiment I artificially set the
ingress bandwidth to 1/4 actual and ran a few speed & other tests. ECN
marks worked a treat.
Also, in terms of Openwrt/cerowrt, the versions of cake/tc-adv have been
behind those in the source repositories of sch_cake & tc-adv. As of
approx 10:00 GMT Oct 18th 2015 (and compile/run test on Archer C7 v2) I
updated ceropackages-3.10 to point to the latest commits to those source
repositories. Those commits are
256fbf86642f7e180d507be2c0824c03536ac140 in Dave's sch_cake & tc-adv
I hope that explanation in some way helps :-)
