t4vf_pktgl_to_skb(9)

💅 t4vf_pktgl_to_skb — a Kernel API Manual moment ✨

okay so bestie, welcome to section 9 of the Kernel API Manual — yes we're in the kernel, yes we're in the networking girlies' corner, and yes this page is about t4vf_pktgl_to_skb(9) 🎀

---

🌸 NAME 🌸

t4vf_pktgl_to_skb — literally builds an sk_buff out of a packet gather list, no cap 🫶

---

✨ SYNOPSIS ✨

struct sk_buff * t4vf_pktgl_to_skb (const struct pkt_gl *gl , unsigned
       int skb_len , unsigned int pull_len );

like, that's the whole signature, she's cute, she takes three things and returns a pointer 💖

---

🦋 ARGUMENTS 🦋

• gl — the gather list itself, the main character of this whole operation 👑
• skb_len — the size of the sk_buff main body if it carries fragments (conditional queen behaviour fr fr)
• pull_len — how much data we're moving to the sk_buff's main body 🎀

---

💀 DESCRIPTION 💀

So what she does: builds an sk_buff from the given packet gather list. That's it, that's the vibe 🌈

Returns the sk_buff — or NULL if the sk_buff allocation failed 😭 like if the allocation said "not today", you get NULL, and that's a real thing you gotta handle, no shortcuts bestie.

ngl the NULL return is not a suggestion, it's giving "check me or perish" 💅 so go check it.
