       A structure used to configure an Rx ring of an Ethernet port.

       Definition at line 1125 of file rte_ethdev.h.

structrte_eth_threshrx_thresh
       Rx ring threshold registers.

       Definition at line 1126 of file rte_ethdev.h.

   uint16_trx_free_thresh
       Drives the freeing of Rx descriptors.

       Definition at line 1127 of file rte_ethdev.h.

   uint8_trx_drop_en
       Drop packets if no descriptors are available.

       Definition at line 1128 of file rte_ethdev.h.

   uint8_trx_deferred_start
       Do not start queue with rte_eth_dev_start().

       Definition at line 1129 of file rte_ethdev.h.

   uint16_trx_nseg
       Number of descriptions in rx_seg array.

       Definition at line 1130 of file rte_ethdev.h.

   uint16_tshare_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 1137 of file rte_ethdev.h.

   uint16_tshare_qid
       Shared Rx queue ID in group

       Definition at line 1138 of file rte_ethdev.h.

   uint64_toffloads
       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 1144 of file rte_ethdev.h.

   unionrte_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 1152 of file rte_ethdev.h.

   structrte_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.

       Definition at line 1173 of file rte_ethdev.h.

   uint64_treserved_64s[2]
       < Number of Rx mempools Reserved for future fields

       Definition at line 1176 of file rte_ethdev.h.

   void*reserved_ptrs[2]
       Reserved for future fields
