e1000_free_rx_resources(9)

💖 e1000_free_rx_resources — from the Kernel API Manual, bestie 💖

okay so grab a snack 🍓 because we're reading e1000_free_rx_resources, and yes it's straight out of the Kernel API Manual. this one is short and sweet — it's literally the cleanup crew of the e1000 receive path, and honestly? underrated. let's get into it 💅

---

✨ NAME ✨

e1000_free_rx_resources — Free Rx Resources. that's it, that's the job. 🎀

---

🌸 SYNOPSIS 🌸

void e1000_free_rx_resources (struct e1000_adapter *adapter , struct
e1000_rx_ring *rx_ring );

it returns void, so no sneaky return values to check, no "did it work" arc. it just does the thing. 🫶

---

🦋 ARGUMENTS 🦋

• adapter — the board private structure. like, the whole adapter's personal little diary of state, and it's what you're handing over. 👑
• rx_ring — the ring you're cleaning the resources from. that's the one getting the glow-up (well, the opposite of a glow-up — the tidy-up). 🧹

---

⭐ DESCRIPTION ⭐

Free all receive software resources. that's the whole vibe check: everything Rx that lived in software gets released. no cap, no leftover mess, just clean. ✨

and that's the whole page, bestie 💜 the footer says the source/version is ./drivers/net/ethernet/intel/e... and it's dated October 2026 — so like, future-coded but make it kernel docs. obsessed. periodt. 👑🦋
