+=========================
+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.
