    XL710 priority queues

    clivep

      I have an XL710 VSI that is running in a VF and uses RSS queuing across multiple queues on input. I want to create a separate priority queue that will receive only certain frame types eg LACP. Is the best way to achieve this as follows:

      1. create a second VSI on this VF (with the same MAC address) with one receive queue.

      2. allocate an L2 filter on the PF as part of that VSI creation that will filter for the desired frames.

      Then the desired frames will be received in the 2nd VSI's rcv queue?

            Hi clivep,

             

                      Good day. Here is what you can try either of the following:

             

            1)  Create an extra queue in the VF and apply an ethertype filter to direct the packets to that queue.

            2)  Or create a new VSi, same MAC and apply an Ethertype control filter for the VSi and have a single queue there.

             

                      To debugfs the interface you can add a ethertype control filter to experiment.

            Echo add ethtype filter <ethtype> <to_queue> > command
            Echo rem ethtype filter <ethtype> <to_queue> > command

             

                    hope this helps.
