💅 rte_eth_rxseg_capa

okay bestie, pull up a chair 🎀 today's main character is rte_eth_rxseg_capa, a lil struct from the DPDK fam that tells you what an Ethernet device can actually do when it comes to splitting up Rx buffers. yeah. segmentation. we love a niche icon ✨

✨ NAME ✨

rte_eth_rxseg_capa — the struct that's like "here's what your NIC can do with Rx buffer segments, no cap" 🦋

✨ SYNOPSIS ✨

#include <rte_ethdev.h>

🌸 Data Fields 🌸

__extension__ uint32_t multi_pools:1
uint32_t offset_allowed:1
uint32_t offset_align_log2:4
uint16_t max_nseg
uint16_t reserved

like, that's the whole squad right there 👑 and yes the bitfield widths are exact, don't come for me 🙈

✨ Detailed Description ✨

Warning 💀 EXPERIMENTAL: this structure may change without prior notice.

so what IS it? it's the Ethernet device Rx buffer segmentation capabilities struct — literally the vibe check for how a device likes its receive buffers chopped up 💖

fr fr, it lives at Definition at line 1756 of file rte_ethdev.h. 📍

✨ Field Documentation ✨

  • __extension__ uint32_t multi_pools — the "can I receive into multiple pools tho" flag 🏊‍♀️ Supports receiving to multiple pools. Definition at line 1758 of file rte_ethdev.h.
  • uint32_t offset_allowed — does this device fw buffer offsets? Supports buffer offsets. Definition at line 1759 of file rte_ethdev.h. 🫶
  • uint32_t offset_align_log2 — the alignment requirement, in log2 form because of course it is 😭 Required offset alignment. Definition at line 1760 of file rte_ethdev.h.
  • uint16_t max_nseg — how many segments you're allowed to split into, maximum edition. Maximum amount of segments to split. Definition at line 1761 of file rte_ethdev.h. 🔥
  • uint16_t reserved — bestie this one's just vibes. Reserved field. Definition at line 1762 of file rte_ethdev.h. 💀
