How to clear ISP traffic with OpenWrt?

@N1K

No but 0x40 and 0x80 and thousands of ip6 flowlabels.

Flowlabels are irrelevant, cake does not use those to select a packets priority tier.

TOS 0x40: CS2 -> cake's Video tin
TOS 0x80: CS4 -> cake's Voice tin

So I can see your lack a happiness. BUT why is dscpclassify not marking these? Are these terminated by the router itself and/or are the connections initiated from the outside?

@N1K

How do i do that correctly ?

Good question, I would probably take inspiration from @lynx at:

CAKE w/ DSCPs - cake-qos-simple

Thanks so much @tohojo and @dave14305 - this simplifies things significantly. @tohojo might it not still be an idea to further include switches for the cake qdisc that enables or disables marking? I'm also curious about your thoughts about ECN Vs dropping in general. Most mobile operators (including Vodafone UK it seems) bleach the ECN bits. How beneficial would it be if they did not? I see that you and @moeller0 discussed here: enabling or disabling marking based on rate.

and try something along the lines of

tc filter add dev "${ul_if}" parent 1: protocol ip matchall action pedit ex munge ip dsfield set 0 retain 0xfc
tc filter add dev "${ul_if}" parent 1: protocol ip6 matchall action pedit ex munge ip6 traffic_class set 0 retain 0xfc

EDIT: Thanks @dave14305, as I said this was not tested (and apparently not even sanity checked )

Note, I only looked at man tc-pedit and composed this in this editor, so this is neither tested nor guaranteed to not explode.... but it should give you an idea how to proceed....
