iavf_verify_api_ver(9)

🦋 iavf_verify_api_ver(9) — the vibe check for your API versions 🦋

okay so this is a page from the Kernel API Manual, and bestie, it's a whole little function in ./drivers/net/ethernet/intel/iavf. Let's get into it 💅

---

✨ NAME ✨

iavf_verify_api_ver — and that's... literally it 💀 the description line is blank in the original, no cap. Not me leaving it empty, it's just giving mysterious main character energy. Moving on 🫶

---

⭐ SYNOPSIS ⭐

int iavf_verify_api_ver (struct iavf_adapter *adapter );

---

🎀 ARGUMENTS 🎀

• adapter — the adapter structure. that's the whole one-liner, she's lowkey a woman of few words 🌸

---

💖 DESCRIPTION 💖

okay so what she does: this function compares the API versions with the PF (that's the physical function, iykyk). Simple queen behaviour.

⚠️ important rule: it must be called after the admin queue is initialized. like, do not come for her before the admin queue is ready, she will not know what to do with you 😭

here's the return value tea ☕:

• returns 0 if the API versions match — slay, we love a happy ending ✨
• returns -EIO if they do not match — the vibes are off, the versions are off, it's giving incompatible 💔
• returns IAVF_ERR_ADMIN_QUEUE_NO_WORK if the admin queue is empty — nobody home, the queue is literally on airplane mode 🙈
• and any errors coming from the firmware are propagated, so whatever the firmware is going through, you're going through it too fr fr 🫶
