💖 rte_pmd_mlx5_geneve_tlv 💖

okay bestie, so this is a page from the Library Functions Manual, and it's literally all about rte_pmd_mlx5_geneve_tlv 🦋 — a struct that lives in DPDK land and helps you build a parser for a single GENEVE TLV option. no cap, one option per struct, that's the whole vibe.

✨ NAME ✨

rte_pmd_mlx5_geneve_tlv — the user config struct you fill out to make a parser for one single GENEVE TLV option 💅

🌸 SYNOPSIS 🌸

#include <rte_pmd_mlx5.h>

🎀 Data Fields

• rte_be16_t option_class
• uint8_t option_type
• uint8_t option_len

🫶 Detailed Description 🫶

It's a user configuration structure used to create a parser for a single GENEVE TLV option. that's it, that's the job. you fill it in, it tells the parser what to look at 👑

fr fr, it's defined at line 288 of the file rte_pmd_mlx5.h — go look if you don't believe me 💀

👑 Field Documentation 👑

🌈 rte_be16_t option_class

The class of the GENEVE TLV option. pls note it's relevant only when 'match_on_class_mode' is 1 🙈 like it's literally just sitting there being ignored otherwise.

Defined at line 293 of rte_pmd_mlx5.h ✨

🍓 uint8_t option_type

The type of the GENEVE TLV option. this field is the identifier of the option — the little name tag it wears at the function 🏷️

Defined at line 298 of rte_pmd_mlx5.h ✨

🦋 uint8_t option_len

The length of the GENEVE TLV option data, excluding the option header, measured in DW granularity. header doesn't count, bestie, we're only measuring the data 💅

Defined at line 303 of rte_pmd_mlx5.h ✨

💜 uint8_t match_on_class_mode

The indicator of what role the class field plays in this option, and it's a whole little menu:

• 0 — class is ignored, we don't know her 🙈
• 1 — class is fixed, so the class defines the option along with the type (it's a package deal 💞)
• 2 — class matching per flow 🌊

Defined at line 310 of rte_pmd_mlx5.h ✨

🌸 uint8_t offset

The offset of the first sample, in DW granularity. this offset is relative to the first of the option data 📍. and the 'match_data_mask' corresponds to option data since this offset — so yes, it all shifts together, they're a matched set 🫶

Defined at line 316 of rte_pmd_mlx5.h ✨

⭐ uint8_t sample_len

The number of DW to sample 🎯. this field describes the length of 'match_data_mask', in DW granularity.

Defined at line 322 of rte_pmd_mlx5.h ✨

🔥 rte_be32_t* match_data_mask

An array of DWs where each bit marks if this bit should be sampled. and here's the tea: each nonzero DW consumes one DW from a maximum of 7 DW in total 😭 so budget accordingly, you only get 7.

Defined at line 327 of rte_pmd_mlx5.h ✨
