e1000_poll_for_ack(9)

💅 e1000_poll_for_ack — wait for that message acknowledgment, bestie

okay so real talk, this is a page from the Kernel API Manual (section 9, the kernel-API girlies know) and it's called e1000_poll_for_ack. It's short. It's sweet. It does exactly one thing and honestly? It ate. ✨

---

🌸 SYNOPSIS 🌸

s32 e1000_poll_for_ack (struct e1000_hw *hw );

that's it. one function, one argument, one s32 coming back at you. no cap. 🎀

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure. that's the hardware struct, the whole vibe of the device, you hand it over and it does the thing. 🫶

---

💖 DESCRIPTION 💖

okay so here's the whole plot: this function returns SUCCESS if it successfully received a message acknowledgment.

that's the entire personality. it polls, it waits, it wants that ack, and if the ack shows up it's giving SUCCESS. literally the whole arc of this function. 👑

ngl, that's genuinely all the original says — no extra lore, no secret flags, no hidden defaults. the doc is a one-liner and we respect it.
