lro_add_page(9)

💅 lro_add_page — the kernel API manual, but make it cute 🎀

okay so bestie, we're in the Kernel API Manual today and the function on the menu is lro_add_page(9). yes she's a (9) section girlie, kernel-API coded, and she does exactly one thing but she does it well. let's get into it ✨

---

🌸 NAME 🌸

lro_add_page — add a page chunk to an LRO session. literally that's her whole job. one page chunk, one LRO session, slay 💅

---

✨ SYNOPSIS ✨

void lro_add_page (struct adapter *adap , struct sge_qset *qs , struct
       sge_fl *fl , int len , int complete );

she takes five things and returns void, meaning she gives you nothing back but vibes 🫶

---

🦋 ARGUMENTS 🦋

• adap — the adapter. the main character of the hardware world 👑
• qs — the associated queue set. she comes as a package deal.
• fl — the free list containing the page chunk to add. that's where the page chunk's been living rent free 🏠
• len — packet length. a number. don't overthink her.
• complete — Indicates the last fragment of a frame. so like... the final piece of the puzzle, the last text in the group chat, the 💀 of it all.

---

🔥 DESCRIPTION 🔥

Add a received packet contained in a page chunk to an existing LRO session.

that's it. that's the whole thing. she takes a packet that's chillin inside a page chunk, and she drops it into the LRO session that's already going. no cap, no extra steps, no notes 🧚
