rte_port_i...ltr_config(3)

💅 NAME 💅

rte_port_in_action_fltr_config — bestie's little struct for telling the packet pipeline which packets get to go where 🎀

---

✨ SYNOPSIS ✨

#include <rte_port_in_action.h>

🦋 Data Fields 🦋

uint32_t key_offset
uint8_t key_mask[RTE_PORT_IN_ACTION_FLTR_KEY_SIZE]
uint8_t key[RTE_PORT_IN_ACTION_FLTR_KEY_SIZE]
int filter_on_match
uint32_t port_id

---

🌸 DETAILED DESCRIPTION 🌸

Okay so. This is the filter action config, and it lives per action profile — like, one of these per profile, not one globally. It's giving "which packets am I looking at, and where do I send them" 💖

Defined at line 76 of rte_port_in_action.h, no cap.

👑 FIELD DOCUMENTATION 👑

⭐ uint32_t key_offset

Where in the input packet buffer the key actually starts. And listen — offset 0 points to the first byte of the MBUF structure, not to the packet data. The struct is the main character first, the payload comes later, iykyk 😭

Defined at line 80 of rte_port_in_action.h.

🧚 uint8_t key_mask[RTE_PORT_IN_ACTION_FLTR_KEY_SIZE]

The key mask, babes. It's literally just the mask 🌈

Defined at line 83 of rte_port_in_action.h.

🫶 uint8_t key[RTE_PORT_IN_ACTION_FLTR_KEY_SIZE]

The key value. That's the vibe 💜

Defined at line 86 of rte_port_in_action.h.

🔥 int filter_on_match

This one's the personality of the whole struct, fr fr:

• When it's non-zero, every input packet that matches the key (with the key_mask applied, don't forget the mask bestie) gets sent to the pipeline output port port_id.
• When it's zero, it flips — every input packet that does NOT match the key (again with key_mask applied) gets sent to the pipeline output port port_id.

So like, matching or not-matching, your choice 💅

Defined at line 93 of rte_port_in_action.h.

🎀 uint32_t port_id

The pipeline output port ID where the filtered input packets get sent. Good news: this one can be updated later — it's not locked in, she's flexible ✨
