Part Number: AM5726
Processor SDK Linux 126.96.36.199 RT
Kernel 4.4.41 (RealTime)
We would like to use the mqprio qdisc to get important traffic with very low jitter (ideally <200us for a packet every 4ms) and additionally TCP traffic for e.g. showing pictures in a UI (high volume). Apart from throtteling the data from the application side, we thought that tc qdisc mqprio would be the ideal solution, so we can filter the important traffic to the highest priority hw queue.
However, this does not work, when we do
tc qdisc add dev eth1 root handle 1: mqprio num_tc 3 map 2 2 1 1 2 2 2 2 2 2 2 2 2 2 2 2 queues 1@0 1@1 2@2 hw 1
we get “RTNETLINK answers: Operation not supported”
A patch suggested at http://patches.linaro.org/patch/136371/ seems not to be applicable to that kernel version.
Are there ways to configure the linux kernel so that this can be made functional?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

While we could introduce individual patches carefully, we would be glad to stay with the Kernel from the 188.8.131.52 SDK due to achieved test progress
