idpf_del_flow_steer(9)

💅 idpf_del_flow_steer(9) — bestie edition

okay so real talk, this is a page straight out of the Kernel API Manual ✨ and it's about deleting a Flow Steering filter. yes, deleting. we love a little cleanup moment 💖

---

✨ NAME ✨

idpf_del_flow_steer — delete a Flow Steering filter 🗑️🌸

like, it literally does what it says on the tin, no cap.

---

🦋 SYNOPSIS 🦋

int idpf_del_flow_steer (struct net_device *netdev , struct
       ethtool_rxnfc *cmd );

that's the whole vibe right there 👑 — returns an int, takes two pointers, we move.

---

🎀 ARGUMENTS 🎀

• netdev — the network interface device structure 🫶 like, the actual NIC she's working with
• cmd — command to add Flow Steering filter 😭 (yes, the manpage says add here even though we're deleting, we're just reporting the facts, don't come for me)

---

⭐ RETURN ⭐

0 on success and negative values for failure 💀 — so if you get a negative back, something went sideways, periodt.

ngl, always check your return value bestie, it's giving main character energy to ignore errors and it never ends well 🙈
