idpf_send_create_vport_msg(9)

✨ idpf_send_create_vport_msg ✨

okay so bestie, we're in the Kernel API Manual today — section 9 ofc — and the function we're stanning is idpf_send_create_vport_msg. yes it's a whole mouthful, no I will not be shortening it, and yes it slaps 💅

---

🌸 NAME 🌸

idpf_send_create_vport_msg — send virtchnl create vport message 🦋

like, that's the whole job. it sends the message. the vport gets created. main character behaviour fr.

---

🎀 SYNOPSIS 🎀

int idpf_send_create_vport_msg (struct idpf_adapter *adapter , struct
idpf_vport_max_q *max_q );

yes the line break in the middle of the struct is real, that's just how the manual renders it, we don't gatekeep 💖

---

💜 ARGUMENTS 💜

• adapter — the driver's own private structure 🫶 like, this is your struct idpf_adapter * and it's yours, the driver's little secret stash of state.
• max_q — the vport max queue info 🌈 literally what it says on the tin: the max queue deets for the vport.

---

🔥 DESCRIPTION 🔥

so the vibe here is: send virtchnl creae vport message 😭 (yes, creae — that's the typo as written in the manual, and honestly? iconic. we're leaving it. it's canon now. 🎀)

and then the returns, which is the part where you actually pay attention bestie:

Returns 0 on success, negative on failure ⭐

that's it. that's the contract. zero means slay, negative means something went sideways and you handle it. periodt. 💅
