i40e_vc_send_msg_to_vf(9)

💌 i40e_vc_send_msg_to_vf(9) — from the Kernel API Manual, bestie

okay so picture this: it's a kernel API manual page, section 9, and the star of the show is i40e_vc_send_msg_to_vf. That's the whole title, no notes. The NAME section down there is literally just the function name and a dash, and honestly? Iconic minimalism. She said "my name is enough." 💅

✨ NAME ✨

i40e_vc_send_msg_to_vf —

(that's it. that's the name section. the dash is doing a lot of heavy lifting today 🎀)

---

🌸 SYNOPSIS 🌸

int i40e_vc_send_msg_to_vf (struct i40e_vf *vf , u32 v_opcode , u32
v_retval , u8 *msg , u16 msglen );

like, look at her. five parameters, returns an int, zero chill. 🦋

---

🧚 ARGUMENTS 🧚

• vf — pointer to the VF info. this is the VF's whole personality file, so treat her right 🫶
• v_opcode — the virtual channel opcode. the "what are we even doing here" of the message 💫
• v_retval — the virtual channel return value. the vibe check result, basically ⭐
• msg — pointer to the msg buffer. the actual message lives here, say hi to it for me 😭
• msglen — msg length. how much of that buffer is real and how much is just... space 🌈

---

💖 DESCRIPTION 💖

send msg to VF.

(yes queen, that's the entire description. four words. she's efficient, she's booked, she's busy. no cap.) 🔥

💀 real talk though: this page gives you the signature and the one-line purpose, and the cross-references do the rest of the lore. read them if you want the full story, bestie — i'm not out here inventing behaviour that isn't written down, that's not the vibe 🙈
