💌 ixgbevf_write_mbx_vf_legacy(9)

okay so bestie, welcome to the ixgbevf_write_mbx_vf_legacy(9) page — part of the Kernel API Manual and honestly it's giving "tiny function, huge friend group" energy. It's literally a mailbox-writing function for the Intel ixgbevf driver and it's here to help you drop a message into that buffer. 🎀

---

✨ SYNOPSIS ✨

s32 ixgbevf_write_mbx_vf_legacy (struct ixgbe_hw *hw , u32 *msg , u16
size );

like… look at that signature. s32 return, three args, no notes. icon behavior. 💅

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure. yes, the whole hardware struct, she's the main character here 👑
• msg — The message buffer. this is where your actual message lives ✨
• size — Length of buffer. gotta tell her how much to read, no cap 🫶

---

🌸 DESCRIPTION 🌸

returns 0 if it successfully copied message into the buffer 🌈

that's it, that's the whole description — no extra lore, no hidden DLC, just: success = 0. genuinely so clean. 🔥

ngl bestie, the page is short but the guest list is long. read the see-also list before you go poking at mailboxes — it's all connected. 🧚
