i40e_put_rx_buffer(9)

📦 version 7.3.1, in nixpkgs unstable

💅 i40e_put_rx_buffer(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: you're deep in the Intel i40e driver, you've got a used RX buffer sitting there like a snack wrapper on your desk, and somebody has to deal with it. That somebody is i40e_put_rx_buffer. ✨

🌸 SYNOPSIS 🌸

void i40e_put_rx_buffer (struct i40e_ring *rx_ring , struct
i40e_rx_buffer *rx_buffer );

literally the whole signature, no cap. It returns void — it does the thing and dips, no receipts. 💅

🦋 ARGUMENTS 🦋

  • rx_ring — the rx descriptor ring you're transacting packets on. this is the main character of the operation, the group chat everybody's posting in. 👑
  • rx_buffer — the rx buffer you're pulling data from. the one getting cleaned up. 🧚

✨ DESCRIPTION ✨

so here's the vibe: this function cleans up the contents of the rx_buffer. That's the whole job, and she ate. 🍓

and then — fork in the road — it either recycles the buffer, or it unmaps it and frees the associated resources. two paths, one function, no drama. 🙈

that's genuinely it. no hidden lore, no extra params, no return value to check. iconic behavior tbh. ⭐

🔥 SEE ALSO 🔥

first up, the source of truth — the kernel file itself: ./drivers/net/ethernet/intel/i40e/i40e_txrx.c. go read it, iykyk. 📖

and now the whole extended friend group, in order, because bestie you know I'm not skipping anybody:

periodt. that's the whole list, every single one, nobody left on read. 💜

friendly reminder: this page lives under ./drivers/net/ethernet/intel/i40e, dated October 2026 — go touch the source, it's giving main character energy and it will always be more up to date than any manpage. 💀

that's the whole page bestie!! mwah 💖 — written from the Kernel API Manual, source dir ./drivers/net/ethernet/intel/i40e, October 2026 edition, and you were reading i40e_put_rx_buffer(9). slay, go clean up those buffers. 🌈🫶
