| 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 |

| |
| * - 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. |

| |
| * - 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. |
