Field Documentation

uint16_t nb_max

Max allowed number of descriptors.

Definition at line 1153 of file rte_ethdev.h.

uint16_t nb_min

Min allowed number of descriptors.

Definition at line 1154 of file rte_ethdev.h.

uint16_t nb_align

Number of descriptors should be aligned to.

Definition at line 1155 of file rte_ethdev.h.

uint16_t nb_seg_max

Max allowed number of segments per whole packet.

  • For TSO packet this is the total number of data descriptors allowed by device.

uint16_t nb_mtu_seg_max

Max number of segments per one MTU.

  • For non-TSO packet, this is the maximum allowed number of segments in a single transmit packet.
  • For TSO packet each segment within the TSO may span up to this value.
