Hi list,
We are using a couple of X710-T4L cards in an experimental
testbed. The computer with the cards is currently manjaro linux
5.17rc7 kernel, and cards have been updated with the latest nvm
8.60. As part of the work we wish to periodically change the
shapers' max_rate parameter.
We set up the qdisc as follows:
# tc qdisc replace dev <interface> root mqprio num_tc 1 hw 1 mode
channel shaper bw_rlimit min_rate 0Mbit max_rate 500Mbit map 0 0
0 0 0 0 0 0 queues 1@0
This works well and we are able to confirm the 500Mbit limit
experimentally.
However, when we try to change the speed:
# tc qdisc change dev <interface> root mqprio num_tc 1 hw 1 mode
channel shaper bw_rlimit min_rate 0Mbit max_rate 200Mbit map 0 0
0 0 0 0 0 0 queues 1@0
we get the following error message:
Change operation is not supported by specified qdisc
We are also unable use "replace" a second time.
I know our use case is a little unusual, but it is simple. Does
anyone have any ideas what the problem could be and how we can fix
it or work around it?
Many thanks,
David
