e1000_flush_rx_ring(9)

💖 e1000_flush_rx_ring — the kernel API manual, bestie edition 💖

okay so real talk: this page lives in the Kernel API Manual (section 9, aka the "kernel routines" girlies), and the function's whole name is e1000_flush_rx_ring. Say it with me. Slay. 🎀

---

✨ NAME ✨

e1000_flush_rx_ring — remove all descriptors from the rx_ring</p> 💅

---

🌸 SYNOPSIS 🌸

void e1000_flush_rx_ring (struct e1000_adapter *adapter );

that's it. that's the whole vibe. void return, one pointer, no drama. 🦋

---

🧚 ARGUMENTS 🧚

• adapter — board private structure. like, the adapter's own little private struct where it keeps its business. mind yours. 🙈

---

🔥 DESCRIPTION 🔥

so what does it actually do? no cap:

Mark all descriptors in the RX ring as consumed and disable the rx ring. 🫶

that's the entire assignment and it ate. every descriptor in that ring gets flagged as consumed, and the rx ring itself gets switched off. iconic behavior, zero notes. ✨

mwah 💋 that's the whole page. every option, every cross-reference, nothing dropped. iykyk. 💜

side note bestie: this page is from ./drivers/net/ethernet/intel/e... (yes, the manual genuinely truncates it like that, I'm not doing it to be cute) and it's dated October 2026, so it's basically from the future. time traveler behavior fr fr. 🦋✨

take care of your rings, drink water, and remember: consumed descriptors are consumed. periodt. 💅🎀
