rx_offload(9)

💖 rx_offload(9) — Kernel API Manual 💖

okay so bestie, welcome to rx_offload — it's a kernel API page from the Kernel API Manual and it's lowkey tiny but it's doing Real Work. no cap. let's get into it 🫶

---

✨ NAME ✨

rx_offload — process a received offload packet 💌

---

🌸 SYNOPSIS 🌸

int rx_offload (struct t3cdev *tdev , struct sge_rspq *rq , struct
sk_buff *skb , struct sk_buff *rx_gather[] , unsigned int gather_idx );

like yes she's five arguments long and she's serving, we love a signature with range 👑

---

🎀 ARGUMENTS 🎀

• tdev — the offload device that's receiving the packet. the one catching feelings, basically 🥺
• rq — the response queue that received the packet. that's her home base, that's where she landed 💅
• skb — the packet. the main character. the actual thing ✨
• rx_gather — a gather list of packets, for when we're building a bundle. squad assembly in progress 🧚
• gather_idx — index of the next available slot in the bundle. keep track bestie, keep track 📍

---

🦋 DESCRIPTION 🦋

so what does she do? she processes an ingress offload packet and adds it to the offload ingress queue. that's it, that's the whole vibe. then she returns the index of the next available slot in the bundle — so you know exactly where to drop the next one. iconic behavior, honestly 🌈

ngl this is the entire description in the original page, so don't come for me — she's short but she's precise 💀
