🫶 mlx5hws_context_close — bestie edition

okay so this is a page from the Kernel API Manual, and it's about one (1) little function that closes your direct hardware steering context. tiny page, huge "i'm done here" energy 💅 let's get into it.

---

✨ NAME ✨

mlx5hws_context_close — closes a context that's being used for direct hardware steering. that's it, that's the job, and she does it flawlessly 🎀

---

🌸 SYNOPSIS 🌸

int mlx5hws_context_close (struct mlx5hws_context *ctx );

like. look at her. one argument, returns an int, no notes 👑

---

🦋 ARGUMENTS 🦋

• ctx — the mlx5hws context you wanna close. like literally the thing you're shutting down. hand her over and let her cook 🔥

---

⭐ RETURN ⭐

returns zero on success, and non zero otherwise. so 0 = slay, anything else = something went sideways 😭 (the page doesn't elaborate and honestly neither will i, that's the whole lore).

quick vibe check bestie: this page doesn't say what happens if you close a context twice, or what the actual non zero error codes are. so i'm not gonna invent them either 🤷‍♀️ the manpage said what it said.

this icon of a page came out of ./drivers/net/ethernet/mellano... and it's dated October 2026 — so yeah, she's from the future and she's still just telling you to close your context 🫶✨ bye bestie, go free your resources 💜
