STRUCT EFX_RSS_CONTEXT_PRIV(9)

💅 struct efx_rss_context_priv(9) — the Kernel API Manual moment 🎀

---

✨ NAME ✨

struct efx_rss_context_priv — literally the driver's own private little data stash for an RSS context, bestie 💖

---

🌸 SYNOPSIS 🌸

struct efx_rss_context_priv {
    u32 context_id;
    bool rx_hash_udp_4tuple;
 };

okay so that's the whole struct, no cap — two members, and yes the closing brace in the original has that one extra space before it, we keep it exactly like that because we respect the source 🫶

---

🦋 MEMBERS 🦋

• context_id — this is the RSS_CONTEXT_ID that MC firmware handed back to us 👑. But plot twist: if this context isn't actually present on the NIC, it's EFX_MCDI_RSS_CONTEXT_INVALID instead. it's giving "placeholder value energy" 💀
• rx_hash_udp_4tuple — a bool, and it's exactly what it sounds like: UDP 4-tuple hashing is enabled 🔥. one little flag, carrying the whole vibe check for the UDP hashing situation ✨

lowkey important reminder: that <pink>invalid</pink> sentinel isn't a real context id, it's the "this one's not on the NIC" signal. don't go treating it like a normal id, i'm begging 🙈

and that's the page!! source lives over in ./drivers/net/ethernet/sfc, the version stamp says October 2026, and it's filed under struct efx_rss_context_priv(9) 🌈 — slay, go forth and hash those 4-tuples, mwah 💅💖⭐
