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.

- 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.
