SQM CABLE DOCSIS 3.1 Settings + Packet Prioritization

hey @moeller0 is this post from you still relevant ?

why should someone do point 4. - 6.1 when it says :
Show Advanced Linklayer Options, (only needed if MTU > 1500)

what will these commands do then ?

did i set up everything correct for low latency gaming ?
