As far as I know not for IFBs; that is the reason why we need tc filters on ingress and can not use netfilter. And why using iptables to map the DSCP to zero will still result in our shaper seeing the DSCP markings from upstream (which I could confirm happening for IPv6, as my ISP conserved flent’s DSCP marks, so I saw nice priority band based stratification in flent's graphics). I think that IFBs predecessor IMQ was different in that regard.
Best Regards
Sebastian
