✨ rte_gso_ctx ✨

okay bestie, welcome to the rte_gso_ctx page 💖 this one lives in section 3 of the manual (Library Functions Manual, for the record), and it's literally the whole mood board for GSO. get comfy 🫶

🌸 NAME 🌸

rte_gso_ctx — no cap, that's the name 💅

🦋 SYNOPSIS 🦋

#include <rte_gso.h>

✨ Data Fields ✨

  • struct rte_mempool * direct_pool
  • struct rte_mempool * indirect_pool
  • uint64_t flag
  • uint32_t gso_types
  • uint16_t gso_size

💜 Detailed Description 💜

it's the GSO context structure, periodt. that's the whole vibe.

Defined at line 37 of file rte_gso.h.

🎀 Field Documentation 🎀

🌈 struct rte_mempool* direct_pool

this is the MBUF pool you use to allocate direct buffers, and those are the ones storing packet headers for GSO segments. iconic header storage behavior 💅

Defined at line 38 of file rte_gso.h.

🧚 struct rte_mempool* indirect_pool

and this one is the MBUF pool for allocating indirect buffers, which get used to locate packet payloads for GSO segments. lowkey the clever part: the indirect buffer doesn't contain any data, it just points to an offset within the packet to segment. it's giving "i know a guy" energy 🫶

Defined at line 42 of file rte_gso.h.

⭐ uint64_t flag

the flag that controls specific attributes of your output segments — like the type of IP ID generated (so, fixed or incremental). basically the little switch that decides how things get stamped ✨

Defined at line 48 of file rte_gso.h.

💖 uint32_t gso_types

the bit mask of required GSO types. the GSO library uses the same macros as the ones describing device TX offloading capabilities (that's the RTE_ETH_TX_OFFLOAD_*_TSO crew) for gso_types. iykyk 🌸

for example, if applications want to segment TCP/IPv4 packets, set RTE_ETH_TX_OFFLOAD_TCP_TSO in gso_types. see? simple, slay ✨

Defined at line 52 of file rte_gso.h.

🍓 uint16_t gso_size

the maximum size of an output GSO segment — that means packet header and payload together, measured in bytes. and listen: it must exceed RTE_GSO_SEG_SIZE_MIN. not optional, not negotiable, bestie 😭

Defined at line 61 of file rte_gso.h.
