iavf_get_rxfh(9)

💖 iavf_get_rxfh(9) — the Kernel API Manual glow-up 🎀

okay so bestie, welcome to the iavf_get_rxfh page from the Kernel API Manual ✨ this one is short and sweet and honestly kind of a vibe. grab a strawberry 🍓 and let's go.

---

✨ NAME ✨

iavf_get_rxfh — get the rx flow hash indirection table 👑

lowkey the whole personality of this function is right there in the name. it gets the indirection table. that's it. that's the gig. 💅

---

🦋 SYNOPSIS 🦋

int iavf_get_rxfh (struct net_device *netdev , struct ethtool_rxfh_param
*rxfh );

yes the signature is literally that. copy it exactly, do not "improve" it, do not reformat it, we do not do that here 🙈

---

🌸 ARGUMENTS 🌸

• netdev — the network interface device structure, aka the whole entire device you're asking about 🫶 this is the main character of the call, ngl.
• rxfh — a pointer to the param struct, and inside it lives indir, key, and hfunc 💫 those three are the ones you care about here, iykyk.

---

🧚 DESCRIPTION 🧚

so what does it do? it reads the indirection table directly from the hardware. like, no middleman, no caching arc, straight to the silicon 🔥 the way that it just goes and asks the hardware itself is honestly iconic.

no cap, that's the full description. short king behavior 👑 it does one thing and it does it well.

---

⭐ RETURN ⭐

returns 0. always. fr fr. zero. every time. no error path, no drama, no plot twist 💀 it is not giving "might fail" energy, it is giving "I always come back with 0" energy ✨

like I said. HUGE family. ate 💅

💜 little reminder bestie: 0 always is a promise, not a suggestion. don't go writing error handling for a return value that is literally never anything else. that's not the vibe check we're passing today 🧚

and that's the page!! 🌸 this one came out of ./drivers/net/ethernet/intel/iavf, dated October 2026, from the Kernel API Manual (that's the iavf_get_rxfh(9) manual, section 9, mwah 💋). slay, go read the source, ily, bye 🫶✨🎀
