✨ mlx5hws_action_create_default_miss — the Kernel API Manual tea ✨

okay so bestie, this is a page from the Kernel API Manual (the mlx5hws_acti...default_miss(9) one, yes the name is a whole mouthful, we don't gatekeep) and it's literally about creating a direct rule default miss action 🎀

---

💖 NAME 💖

mlx5hws_action_create_default_miss — create a direct rule default miss action. The defaults are RX: Drop, TX: Wire. no cap, that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

struct mlx5hws_action * mlx5hws_action_create_default_miss (struct
       mlx5hws_context *ctx , u32 flags );

like, you hand it a context and some flags and it gives you back an action pointer, slay 💅

---

🧚 ARGUMENTS 🧚

• ctx — the context in which the new action will be created. it's giving "where the magic happens" ✨
• flags — action creation flags (enum mlx5hws_action_flags). yes bestie, the enum, use it 🎀

---

⭐ RETURN ⭐

Pointer to mlx5hws_action on success, NULL otherwise. so like… check it, okay? don't be out here dereferencing NULL, that's not the main character energy we want 😭💀
