✨ mlx5hws_context_open(9) ✨

okay bestie, welcome to the mlx5hws_context_open(9) era of the Kernel API Manual 💅 this is the function that opens up a context so you can do direct rule insertion using hardware steering — yes, hardware steering, we're not doing software vibes over here 🔥

---

🎀 NAME 🎀

mlx5hws_context_open — open a context used for direct rule insertion using hardware steering ✨ (that's HWS for short, iykyk)

---

🌸 SYNOPSIS 🌸

struct mlx5hws_context * mlx5hws_context_open (struct mlx5_core_dev
*mdev , struct mlx5hws_context_attr *attr );

---

🦋 ARGUMENTS 🦋

• mdev — the device that's gonna be used for HWS, no cap 🔥 this is your device, bestie, choose wisely.
• attr — the attributes used for context open ✨ like, the whole setting-the-vibe config for your new context.

---

💖 RETURN 💖

a pointer to mlx5hws_context on success 💅 and NULL otherwise 😭 (ngl, NULL is giving "it's not happening bestie" energy).
