arc_emac_poll(9)

💖 arc_emac_poll — NAPI poll handler 💖

okay bestie, welcome to the Kernel API Manual entry for arc_emac_poll ✨ this is the little function that shows up when the network stack is like "hey, got any packets for me?" and this driver has to answer. Let's get into it 🎀

---

🌸 SYNOPSIS 🌸

int arc_emac_poll (struct napi_struct *napi , int budget );

that's the whole vibe: you hand it a napi and a budget, and it gives you back an int. simple, iconic, no notes 💅

---

🦋 ARGUMENTS 🦋

• napi — pointer to a napi_struct structure. yes, THE napi struct, the main character of the NAPI world 👑 this is the one you're polling for.
• budget — how many BDs to process on 1 call. that's it, that's the cap. one call, this many BDs, no overachieving 🍓

---

⭐ RETURN ⭐

Number of processed BDs 💖 that's the count you get back — the actual number of BDs it chewed through on this call. fr fr, that's the return value, nothing else.
