ice_vf_verify_rx_desc(9)

💅 ice_vf_verify_rx_desc — verify received FDIR programming status descriptor ✨

okay so bestie, welcome to the Kernel API Manual 🫶 — this one lives in the ice_vf_verify_rx_desc(9) corner of the universe and it's literally the vibe check for an FDIR programming status descriptor that just showed up in your RX queue 🌸

---

🎀 NAME 🎀

ice_vf_verify_rx_desc — no cap, its whole job is to verify received FDIR programming status descriptor. that's it. that's the function. iconic behaviour honestly 💅

---

⭐ SYNOPSIS ⭐

int ice_vf_verify_rx_desc (struct ice_vf *vf , struct ice_vf_fdir_ctx
*ctx , enum virtchnl_fdir_prgm_status *status );

three args, one int back. she's giving "small function, big responsibilities" energy 👑

---

🦋 ARGUMENTS 🦋

• vf — pointer to the VF info 💖 this is the VF's whole little info situation, handed over as a pointer.
• ctx — FDIR context info for post processing 🧚 like, the context you're gonna need after the fact. post-processing tea.
• status — virtchnl FDIR program status 🌈 the virtchnl-flavoured status of the FDIR program. it's right there in the name bestie.

---

🔥 RETURN 🔥

• 0 on success ✨
• and other on error 😭 (yes, "other". that's the actual wording. we don't know which others. it's a mystery. it's giving suspense.)

ngl bestie, if you're here you're probably deep in the Intel ice driver's VF FDIR code. hydrate. take breaks. the FDIR rabbit hole is real 🫶

and that's the whole page!! 💜 source-wise this came from ./drivers/net/ethernet/intel/i... (yes it's literally truncated in the original, we respect the ellipsis 🙈), dated October 2026, sitting under the ice_vf_verify_rx_desc(9) title in the Kernel API Manual. mwah, bye bestie 💅🎀✨
