i40e_get_rxfh(9)

👑 i40e_get_rxfh — like, the whole Kernel API Manual vibe 💅

okay so bestie, welcome to i40e_get_rxfh(9) — yes that (9) means it's a kernel API manual page, we're in the big leagues now ✨

---

🌸 NAME 🌸

i40e_get_rxfh — get the rx flow hash indirection table 🎀

---

✨ SYNOPSIS ✨

int i40e_get_rxfh (struct net_device *netdev , struct ethtool_rxfh_param
*rxfh );

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure, aka the whole entire device bestie 🫶
• rxfh — a pointer to the param struct, and that struct is carrying indir, key, and hfunc 💖

---

💜 DESCRIPTION 💜

so what does it do? it reads the indirection table directly from the hardware 🔥 no middleman, no vibes-based guessing, straight from the silicon. and it returns 0 on success — iconic behaviour, honestly 👑
