does it use other ports?
rpi4.qos classifies;
UDPCONTROLPT="53,5353,123,67,68,520"
TCPCONTROLPT="53,5353,22,179,853"
as control traffic... if it's now using something else... then it will likely get placed in a lower teir... ( you didn't exactly explain what you mean by problems... last time we spoke... I said to remove the pc from GAMING_MACS as that variable is not suited to mixed traffic devices... ideally you should add it back and not download on the same machine whilst gaming... (or you can download within a VM also) there are another qos scripts that may suit you better also... )
ok... you'd probably still see some benefit from both... but vlan setup+not super high wan connection means less stuffing around if you just wait for more polished versions...
( but technically it's worth testing under wan@vlan conditions also )... i'll put this on my list...
you will get gains... by just enabling basic(default) steering for now...
uci -q set network.globals.packet_steering='1'; uci commit network; /etc/init.d/network restart
[FIRST-SCRIPT/STEERING]
the main problem is sqm getting cpu-bound over around/above 2-300mbps somewhere... so users with high speeds should see roughly 15-30% gains under peak demands...
[SECOND-SCRIPT]
basically just bumps up the min_freq 600000>900000 the rest is likely superfluous... apart from the INTERRUPT-AFFINITY... which ties into SCRIPT1/STEERING
