💖 rte_flow_action_vf(3) 💖

okay bestie, welcome to the Library Functions Manual page for rte_flow_action_vf(3) — yes that's the whole name, that's the vibe, we move. sit down, grab a boba, and let's talk about redirecting packets to virtual functions 🦋

✨ NAME ✨

rte_flow_action_vf — that's it, that's the name, iconic, no notes 💅

🌸 SYNOPSIS 🌸

#include <rte_flow.h>

🎀 Data Fields 🎀

uint32_t original:1
uint32_t reserved:31
uint32_t id

like, three fields, all of them uint32_t, two of them doing bitfield things. slay ✨

💜 Detailed Description 💜

⚠️ Deprecated ⚠️ — bestie I'm so serious, this one is deprecated. it's giving "we're keeping it around but look elsewhere." no cap, go check the alternatives below 👇

🔎 See also

  • RTE_FLOW_ACTION_TYPE_PORT_REPRESENTOR
  • RTE_FLOW_ACTION_TYPE_REPRESENTED_PORT
  • RTE_FLOW_ACTION_TYPE_VF

okay so what does it actually do? RTE_FLOW_ACTION_TYPE_VF directs matching traffic to a given virtual function of the current device. that's the whole main character job. traffic comes in, matches, and gets sent to that VF. periodt 💫

and there's more — packets that get matched by a VF pattern item can be redirected back to their original VF ID instead of the one you specified. cute, right? except 🫠 this parameter may not be available, and it is not guaranteed to work properly if:

  • the VF part is matched by a prior flow rule, or
  • the packets are not addressed to a VF in the first place.

so basically: sometimes it works, sometimes it doesn't, and the manpage is NOT promising you anything. read the room, check your setup, don't come crying to me 😭

🧚 Field Documentation 🧚

uint32_t original

Use original VF ID if possible.

like, if you can send it back to where it came from, do that. "if possible" is doing a LOT of heavy lifting in that sentence though, just saying 🙈

📍 Definition at line 3536 of file rte_flow.h.

uint32_t reserved

Reserved, must be zero.

bestie. it says must be zero. not "should probably be zero," not "zero-ish," ZERO. it's giving strict parent energy. if you write anything else in there you're on your own, I don't make the rules 💀

📍 Definition at line 3537 of file rte_flow.h.

uint32_t id

VF ID.

the ID of the VF. short, sweet, to the point, ate and left no crumbs 👑

📍 Definition at line 3538 of file rte_flow.h.
