Rx ring threshold registers​.

Drives the freeing of Rx descriptors​.

Definition at line 1158 of file rte_ethdev​.h​.

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

Definition at line 1169 of file rte_ethdev​.h​.

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​.
