A structure used to configure an Rx ring of an Ethernet port.
Definition at line 1121 of file rte_ethdev.h.
struct rte_eth_thresh rx_thresh |
Rx ring threshold registers.
Definition at line 1122 of file rte_ethdev.h.
uint16_t rx_free_thresh |
Drives the freeing of Rx descriptors.
Definition at line 1123 of file rte_ethdev.h.
uint8_t rx_drop_en |
Drop packets if no descriptors are available.
Definition at line 1124 of file rte_ethdev.h.
uint8_t rx_deferred_start |
Do not start queue with rte_eth_dev_start().
Definition at line 1125 of file rte_ethdev.h.
uint16_t rx_nseg |
Number of descriptions in rx_seg array.
Definition at line 1126 of file rte_ethdev.h.
uint16_t share_group |
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.
Definition at line 1133 of file rte_ethdev.h.
uint16_t share_qid |
Shared Rx queue ID in group
Definition at line 1134 of file rte_ethdev.h.
uint64_t offloads |
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.
Definition at line 1140 of file rte_ethdev.h.
union rte_eth_rxseg* rx_seg |
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.
Definition at line 1148 of file rte_ethdev.h.
struct rte_mempool** rx_mempools |
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.
