The RTL930x and RTL931x have an ingress and egress bandwidth controller for
each port. They can can be used to reduce the throughput for each port.
They can be programmed via the the DSA flower offloading capabilities. Only
a limited functionality (bytes based rate limiter for ingress/egress) is
supported.
With kmod-sched-act-police, kmod-sched-flower and tc installed, each port
can have its ingress/egress rate limit applied in hardware using:
# tc qdisc del dev lan1 clsact
tc qdisc add dev lan1 clsact
tc filter add dev lan1 ingress flower skip_sw action police rate 100mbit burst 64k conform-exceed drop
tc filter add dev lan1 egress flower skip_sw action police rate 150mbit burst 64k conform-exceed drop
