rte_ib_bth(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

🦋 rte_ib_bth — the InfiniBand Base Transport Header, bestie edition 🦋

Okay so this is rte_ib_bth, a page from the DPDK Library Functions Manual (third section, iykyk), and it's literally just a struct breakdown for the InfiniBand Base Transport Header. It's giving very "here's the receipt for your packet header" energy, and honestly? We stan a documented bitfield. 💅

✨ NAME ✨

rte_ib_bth — that's the whole name, no cap, that's it.

✨ SYNOPSIS ✨

#include <rte_ib.h>

🎀 Data Fields

Here's the whole glow-up of fields, in order, exactly as they sit in the struct:

uint8_t opcode
uint8_t tver:4
uint8_t padcnt:2
uint8_t m:1
uint8_t se:1
rte_be16_t pkey
uint8_t rsvd0:6
uint8_t b:1
uint8_t f:1
uint8_t dst_qp [3]
uint8_t rsvd1:7
uint8_t a:1
uint8_t psn [3]

Look at those bitfields, bestie. :4, :2, :1, :1 — she's packed, she's efficient, she's main character energy for sure. 👑

🌸 Detailed Description 🌸

This is the InfiniBand Base Transport Header according to IB Specification Vol 1-Release-1.4. That's the vibe check: it's a header, it's base, it transports.
