STRUCT VIRTCHNL2_RSS_LUT(9)

🎀 struct virtchnl2_rss_lut(9) — the RSS LUT info glow-up 🎀

okay so bestie, welcome to the struct virtchnl2_rss_lut(9) page in the Kernel API Manual. yes it's a struct, yes it's about the RSS lookup table, and yes we're gonna make it make sense 💅

---

✨ NAME ✨

struct virtchnl2_rss_lut — RSS LUT info. that's it, that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

struct virtchnl2_rss_lut {
    __le32 vport_id;
    __le16 lut_entries_start;
    __le16 lut_entries;
    u8 pad[4];
    __le32 lut[];
};

look at her. five members, one flexible array, zero notes. she's giving minimal main character energy 👑

---

💖 Members 💖

• vport_id — the Vport id. which vport is this LUT for? this one. periodt.
• lut_entries_start — start of LUT entries. where the entries begin, fr fr.
• lut_entries — Number of LUT entrties. 🫶 (yep, "entrties" — that's literally how it's spelled in the source, and honestly? iconic. keeping it exactly as-is, no cap.)
• pad — Padding. it's here to keep things aligned and looking cute. do not perceive it. 🙈
• lut — RSS lookup table. the actual star of the show, the flexible array, the reason we're all here 💫

---

💜 Description 💜

so the PF sends this message to get or set the RSS lookup table. that's the whole job.

⚠️ important caveat bestie: this is only supported if both PF and CP drivers set the VIRTCHNL2_CAP_RSS bit during configuration negotiation. both of them. if either one skips it, this whole thing is a no-go, so do the vibe check first 😭

it's associated with VIRTCHNL2_OP_GET_RSS_LUT and VIRTCHNL2_OP_SET_RSS_LUT — those are the two ops she rolls with 🔥

okay that's the whole page bestie, you ate that 💅✨

and a lil cute sign-off: this one comes from ./include/linux/net/intel and it's dated October 2026 🌈 so like, future-coded but make it kernel. mwah 💋 🎀
