i40e_ddp_does_profile_exist(9)

💅 i40e_ddp_does_profile_exist 💅

okay bestie, welcome to the Kernel API Manual, section 9 — yes we're in the kernel docs and yes we're gonna make it cute. this one's a little function that answers one very important question: is this DDP profile already here or not? 🎀

---

🌸 NAME 🌸

i40e_ddp_does_profile_exist — lowkey just checks if the DDP profile is already loaded. that's the whole gig. ✨

---

🦋 SYNOPSIS 🦋

int i40e_ddp_does_profile_exist (struct i40e_hw *hw , struct
       i40e_profile_info *pinfo );

like, it takes two things and gives you back an int. iconic behavior honestly. 💜

---

🎀 ARGUMENTS 🎀

• hw — the HW data structure, aka the hardware's whole personality file. 🫶
• pinfo — the DDP profile information structure, aka where the profile's deets live. 💖

---

✨ DESCRIPTION ✨

okay so here's the vibe check: it checks if the DDP profile is loaded already. that's it, that's the function. 🧚

and the return values are giving traffic light, so pay attention:

• returns >0 if the profile exists — slay, it's there 👑
• returns 0 if the profile is absent — not me finding nothing 😭
• returns <0 if there's an error — 💀 bestie something went wrong

fr fr, remember that 0 here does not mean success, it means the profile isn't there. different vibe entirely. don't get it twisted. 🙈
