| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31:9 | 0h | RO | Reserved |
| 8:5 | 0h | RO | WQ Maximum Batch Size (MBS) The maximum number of descriptors that can be referenced by a Batch descriptor submitted to this WQ is 2N, where N is the value in this field.If Batch descriptor is supported (as indicated by bit 1 of OPCAP), this field must not be 0 and must not be greater than the Maximum Supported Batch Size field in GENCAP. Otherwise, this field is reserved. It is checked when the WQ is enabled.Software should set this field to the minimum size needed, to limit how long descriptors can block other descriptors behind them. |
| 4:0 | 0h | RW/L | WQ Maximum Transfer Size (MTS) The maximum transfer size that can be specified in a descriptor submitted to this WQ is 2N, where N is the value in this field. This field must not be greater than the Maximum Supported Transfer Size field in GENCAP. It is checked when the WQ is enabled. Software should set this field to the minimum size needed, to limit how long descriptors can block other descriptors behind them. |
