i40e_get_rxnfc(9)

okay bestie, welcome to the Kernel API Manual page for i40e_get_rxnfc(9) 💖 — she's short, she's sweet, she's literally one job and she does it. let's get into it ✨

---

🌸 NAME 🌸

i40e_get_rxnfc — the command that goes and gets your RX flow classification rules 🎀 like, it's the "hey babe show me what rules we've got" of the i40e world. no cap.

---

✨ SYNOPSIS ✨

int i40e_get_rxnfc (struct net_device *netdev , struct ethtool_rxnfc
*cmd , u32 *rule_locs );

that's the whole signature, bestie — three args, and yes the spacing is exactly like that, don't come for me 🫶

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure 🖧 like, the actual NIC we're talking to. she's the main character here, fr.
• cmd — the ethtool rxnfc command 💅 this is the ask — what exactly are we getting, bestie?
• rule_locs — a pointer where the rule data gets stored 📥 i.e. you hand her a spot and she puts the goods there. iconic.

---

💜 DESCRIPTION 💜

Ok so the whole vibe: this one returns Success if the command is supported 👑 that's it. that's the tea. if it's supported you get Success, and if it's not… well, you don't. periodt. 🌈

no extra lore in here, bestie — the manpage keeps it mysterious and honestly? respect. 🙈
