offload_enqueue(9)

💖 offload_enqueue(9) 💖

okay so bestie, this page is from the Kernel API Manual, and it’s short but honestly iconic. It’s literally about adding an offload packet to an SGE offload receive queue. No cap.

🌸 NAME 🌸

offload_enqueue — add an offload packet to an SGE offload receive queue ✨

🎀 SYNOPSIS 🎀

the whole signature is giving minimal and cute:

void offload_enqueue (struct sge_rspq *q , struct sk_buff *skb );

🫶 ARGUMENTS 🫶

• q — the SGE response queue 💅
• skb — the packet 🎀

🦋 DESCRIPTION 🦋

okay so what it does: you add a new offload packet to an SGE response queue’s offload packet queue. That’s the main character move.

and if the packet is the first on the queue, it schedules the RX softirq to process the queue. periodt. 💖
