i tried sqm but isn't enough for me my goal is to prioritize outgoing gaming traffic at any cost with minimum delay i want to make the router favor the outgoing traffic first
what is name of others packages (drr and hhf and others qdisc) i want to try them all 
my firmware is 21.02 rc3 x86_64
Maybe this can help with your initial question?
Mmm, most internet access links are full-duplex, that is incoming (ingress) and outgoing (egress) traffic can flow concurrently, so no need to prioritise egress over ingress traffic. Maybe this 3000+ plus thread can help get you started on your quest?
