Drives the freeing of Rx descriptors.

Drop packets if no descriptors are available.

Do not start queue with rte_eth_dev_start().

Number of descriptions in rx_seg array.

Share group index in Rx domain and switch domain. Non-zero value to enable Rx queue share, zero value disable share. PMD is responsible for Rx queue consistency checks to avoid member port's configuration contradict to each other.

Shared Rx queue ID in group

Per-queue Rx offloads to be set using RTE_ETH_RX_OFFLOAD_* flags. Only offloads set on rx_queue_offload_capa or rx_offload_capa fields on rte_eth_dev_info structure are allowed to be set.

Points to the array of segment descriptions for an entire packet. Array elements are properties for consecutive Rx segments.

The supported capabilities of receiving segmentation is reported in rte_eth_dev_info.rx_seg_capa field.

Array of mempools to allocate Rx buffers from.

This provides support for multiple mbuf pools per Rx queue. The capability is reported in device info via positive max_rx_mempools.

It could be useful for more efficient usage of memory when an application creates different mempools to steer the specific size of the packet.

If many mempools are specified, packets received using Rx burst may belong to any provided mempool. From ethdev user point of view it is undefined how PMD/NIC chooses mempool for a packet.

If Rx scatter is enabled, a packet may be delivered using a chain of mbufs obtained from single mempool or multiple mempools based on the NIC implementation.
