rte_eth_fdir_info(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

💅 rte_eth_fdir_info — like, the whole vibe

Okay bestie, gather round, because this is rte_eth_fdir_info straight out of the DPDK Library Functions Manual, and honestly? It's giving "struct energy" and I'm obsessed. 🦋 This isn't a function you call — it's a struct, a little container of info you get handed back, and it's literally the blueprint for finding out what your flow director can do. No cap.

✨ SYNOPSIS ✨

#include <rte_eth_ctrl.h>

🎀 Data Fields

  • enum rte_fdir_mode mode
  • struct rte_eth_fdir_flex_conf flex_conf
  • uint32_t guarant_spc
  • uint32_t best_spc
  • uint64_t flow_types_mask [RTE_FLOW_MASK_ARRAY_SIZE]
  • uint32_t max_flexpayload
  • uint32_t flex_payload_unit
  • uint32_t max_flex_payload_segment_num
  • uint16_t flex_payload_limit
  • uint32_t flex_bitmask_unit
  • uint32_t max_flex_bitmask_num

🌸 Detailed Description

So this struct is the way to grab the info about your flow director filter — it's the main character of the whole thing. 🌟 It supports RTE_ETH_FILTER_FDIR together with the RTE_ETH_FILTER_INFO operation. iykyk.

What's inside it? The mode, flexible payload configuration information, capabilities and supported flow types, plus all the flexible payload characters. Basically the whole personality. 💖

And why do you care? Because you can get it to help you take specific configurations per device — every NIC gets its own little custom fit. Periodt.

👑 Field Documentation

enum rte_fdir_mode mode

The flow director mode. Literally which mode you're in, bestie. 🧚

Definition at line 441 of file rte_eth_ctrl.h.

struct rte_eth_fdir_flex_conf flex_conf

Flex payload configuration information — all the deets about how your flexible payload is set up. ✨

Definition at line 444 of file rte_eth_ctrl.h.

uint32_t guarant_spc

Guaranteed spaces. It's guaranteed, so you can trust it. 🫶

Definition at line 445 of file rte_eth_ctrl.h.

uint32_t best_spc

Best effort spaces — it tries its best, okay? 😭

Definition at line 446 of file rte_eth_ctrl.h.

uint64_t flow_types_mask[RTE_FLOW_MASK_ARRAY_SIZE]

A bit mask for every supported flow type. Every. Single. One. 💅

Definition at line 448 of file rte_eth_ctrl.h.

uint32_t max_flexpayload

Total flex payload in bytes. Total. Flex. Payload. 🔥

Definition at line 449 of file rte_eth_ctrl.h.

uint32_t flex_payload_unit

Flexible payload unit in bytes. Heads up, this one matters: the size and alignments of all flex payload segments should be multiplies of this value. Not vibes — multiples. Do the math. 🔢

Definition at line 452 of file rte_eth_ctrl.h.

uint32_t max_flex_payload_segment_num

Max number of flexible payload continuous segments. And bestie, each segment should be a multiple of flex_payload_unit. No skipping that. 🎀

Definition at line 455 of file rte_eth_ctrl.h.

uint16_t flex_payload_limit

Maximum src_offset in bytes allowed. Translation: it indicates that src_offset[i] in struct rte_eth_flex_payload_cfg should be less than this value. Stay under the limit, queen. 💜

Definition at line 459 of file rte_eth_ctrl.h.

uint32_t flex_bitmask_unit

Flex bitmask unit in bytes. And yes — the size of flex bitmasks should be a multiple of this value. Consistency is iconic. 🌈

Definition at line 462 of file rte_eth_ctrl.h.

uint32_t max_flex_bitmask_num

Max supported size of flex bitmasks, measured in flex_bitmask_unit. That's it, that's the field. ⭐

Definition at line 464 of file rte_eth_ctrl.h.
