=========================

octeontx2 devlink support

=========================



This document describes the devlink features implemented by the ``octeontx2 AF, PF and VF``

device drivers.



Parameters

==========



The ``octeontx2 PF and VF`` drivers implement the following driver-specific parameters.



.. list-table:: Driver-specific parameters implemented

   :widths: 5 5 5 85



   * - Name

     - Type

     - Mode

     - Description

   * - ``mcam_count``

     - u16

     - runtime

     - Select number of match CAM entries to be allocated for an interface.

       The same is used for ntuple filters of the interface. Supported by

       PF and VF drivers.

     - u32

     - runtime

     - Use to set the quantum which hardware uses for scheduling among transmit queues.

       Hardware uses weighted DWRR algorithm to schedule among all transmit queues.
