Good day everyone! I recently found this interesting project with some positive feedbacks from the communities:
https://forum.openwrt.org/t/qosmate-yet-another-quality-of-service-tool-for-openwrt/207614
However, I'm not sure if this will work with GL's firmware since some of its dependencies may or may not be included or will work properly from GLs own plugin repo. Also, the interfaces are kind of different compared to the vanilla OpenWRT so that's another point of failure. Any thoughts will help or even giving it support for the next update despite being an early project build is even amazing. Thanks everyone!
Dependencies needed:
kmod-sched
ip-full
kmod-veth
tc-full
kmod-netem
kmod-sched-ctinfo
kmod-ifb
kmod-sched-cake
conntrack
