rte_eth_desc_lim(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

💅 rte_eth_desc_lim(3) — the descriptor-limits struct, bestie 💅

okay so this is the Library Functions Manual page for rte_eth_desc_lim(3), and it’s literally the glow-up guide for a struct that holds HW descriptor ring limitations. no cap, it’s giving “small struct, very specific job.” 🫶

🌸 NAME 🌸

rte_eth_desc_lim — the struct that tells you what the HW descriptor ring will and will not allow, and she is very precise about it. ✨

🎀 SYNOPSIS 🎀

#include <rte_ethdev.h>

📦 Data Fields 📦

  • uint16_t nb_max
  • uint16_t nb_min
  • uint16_t nb_align
  • uint16_t nb_seg_max
  • uint16_t nb_mtu_seg_max

💖 Detailed Description 💖

A structure contains information about HW descriptor ring limitations. that’s the whole vibe: it’s the struct that spills the tea on what the hardware descriptor ring can handle. 🦋

🧚 Field Documentation 🧚

uint16_t nb_max 👑

Max allowed number of descriptors.

Definition at line 1365 of file rte_ethdev.h.

uint16_t nb_min 🎀

Min allowed number of descriptors.

Definition at line 1366 of file rte_ethdev.h.

uint16_t nb_align ✨

Number of descriptors should be aligned to.

Definition at line 1367 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.

Definition at line 1377 of file rte_ethdev.h.

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.
