+=========================
+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.
+   * - ``serdes_link``
+     - bool
+     - runtime
+     - Use to initialize and de-initialize SerDes configuration. Command is
+       sent to firmware for SerDes configuration. Supported by PF driver
+
+The ``octeontx2 AF`` driver implements the following driver-specific parameters.
+
+.. list-table:: Driver-specific parameters implemented
+   :widths: 5 5 5 85
+
+   * - Name
+     - Type
+     - Mode
+     - Description
+   * - ``dwrr_mtu``
+     - 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.
