Field Documentation

  uint32_t rx_queue_flags
Flags for handling received packets

Definition at line 159 of file rte_event_eth_rx_adapter.h.

  uint16_t servicing_weight
Relative polling frequency of ethernet receive queue when the adapter uses a service core function for ethernet to event device transfers. If it is set to zero, the Rx queue is interrupt driven (unless rx queue interrupts are not enabled for the ethernet device).

Definition at line 163 of file rte_event_eth_rx_adapter.h.

  struct rte_event ev
The values from the following event fields will be used when queuing mbuf events:

•   event_queue_id: Targeted event queue ID for received packets.

•   event_priority: Event priority of packets from this Rx queue in the event queue relative to other events.

•   sched_type: Scheduling type for packets from this Rx queue.

•   flow_id: If the RTE_ETH_RX_EVENT_ADAPTER_QUEUE_FLOW_ID_VALID bit is set in rx_queue_flags, this flow_id is used for all packets received from this queue. Otherwise the flow ID is set to the RSS hash of the src and dst IPv4/6 addresses.

The event adapter sets ev.event_type to RTE_EVENT_TYPE_ETHDEV in the enqueued event.

  uint16_t vector_sz
Indicates the maximum number for mbufs to combine and form a vector. Should be within

    rte_event_eth_rx_adapter_vector_limits::max_vector_sz Valid when RTE_EVENT_ETH_RX_ADAPTER_QUEUE_EVENT_VECTOR flag is set in

  uint64_t vector_timeout_ns
Indicates the maximum number of nanoseconds to wait for receiving mbufs. Should be within vectorization limits of the adapter

    rte_event_eth_rx_adapter_vector_limits::max_vector_ns Valid when RTE_EVENT_ETH_RX_ADAPTER_QUEUE_EVENT_VECTOR flag is set in

  struct rte_mempool* vector_mp
Indicates the mempool that should be used for allocating rte_event_vector container. Should be created by using rte_event_vector_pool_create. Valid when RTE_EVENT_ETH_RX_ADAPTER_QUEUE_EVENT_VECTOR flag is set in

  uint16_t event_buf_size
event buffer size for this queue
