- =========================
- 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.
- 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.
- The ``octeontx2 PF`` driver implements the following driver-specific parameters.
- .. list-table:: Driver-specific parameters implemented
- :widths: 5 5 5 85
- * - Name
- - Type
- - Mode
- - Description
- * - ``unicast_filter_count``
- - u8
- - runtime
- - Set the maximum number of unicast filters that can be programmed for
- the device. This can be used to achieve better device resource
- utilization, avoiding over consumption of unused MCAM table entries.
