💌 igb_check_for_ack(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, we're being fancy today 🎀 — and today's main character is igb_check_for_ack, a little function that literally just peeks at the mailbox to see if someone slid an ACK into it. lowkey iconic behaviour tbh 👑

---

✨ NAME ✨

igb_check_for_ack — checks to see if someone sent us ACK 💅

like. that's the whole thing. it checks. for an ack. no cap.

---

🦋 SYNOPSIS 🦋

s32 igb_check_for_ack (struct e1000_hw *hw , u16 mbx_id );

copy it exactly like that, spaces and all, because that's how she lives her life 🫶

---

🌸 ARGUMENTS 🌸

• hw — pointer to the HW structure 🧚 she needs to know which hardware we're talking about, obviously
• mbx_id — id of mailbox to check 📬 like which mailbox are we snooping in

---

💖 DESCRIPTION 💖

so the vibe check is simple: this function returns SUCCESS if the Status bit was found 👑 and if it wasn't?? bestie she returns ERR_MBX 😭 that's it, that's the whole plot, no twists, no side quests.

ngl it's giving "short and sweet" and honestly? we love a function that knows what it wants 💀
