Supported by 27 PF and VF drivers. 28 29 The ``octeontx2 AF`` driver implements the following driver-specific parameters. 30 31 .. list-table:: Driver-specific parameters implemented 32 :widths: 5 5 5 85 33 34 * - Name 35 - Type 36 - Mode 37 - Description 38 * - ``dwrr_mtu`` 39 - u32 40 - runtime 41 - Use to set the quantum which hardware uses for scheduling among transmit queues. 42 Hardware uses weighted DWRR algorithm to schedule among all transmit queues. 43 44 The ``octeontx2 PF`` driver implements the following driver-specific parameters. 45 46 .. list-table:: Driver-specific parameters implemented 47 :widths: 5 5 5 85 48 49 * - Name 50 - Type 51 - Mode 52 - Description 53 * - ``unicast_filter_count`` 54 - u8 55 - runtime 56 - Set the maximum number of unicast filters that can be programmed for 57 the device. This can be used to achieve better device resource 58 utilization, avoiding over consumption of unused MCAM table entries.
