## Field Documentation

### uint32\_t max\_nb

\< Event port identifier, the adapter enqueues events to this port and dequeues DMA request events in RTE\_EVENT\_DMA\_ADAPTER\_OP\_FORWARD mode. The adapter can return early if it has processed at least max\_nb DMA ops. This isn't treated as a requirement; batching may cause the adapter to process more than max\_nb DMA ops.
