iavf_chk_linearize(9)

🌸 NAME 🌸

okay so this is the iavf_chk_linearize(9) page from the Kernel API Manual, and it's literally about one thing: checking if there are more than 8 fragments per packet 💅✨

iavf_chk_linearize — check if there are more than 8 fragments per packet 🎀

---

✨ SYNOPSIS ✨

bestie, here's the whole signature, copied exactly because we do not play with code 🫶

bool iavf_chk_linearize (struct sk_buff *skb , int count );

---

🎀 ARGUMENTS 🎀

• skb — the send buffer, aka the packet situation we're looking at 💌
• count — number of buffers used, the count bestie 🔢

---

💅 NOTE 💅

bestie, listen: our HW can't scatter-gather more than 8 fragments to build a packet on the wire 🫠 and so we need to figure out the cases where we need to linearize the skb. no cap, that's the whole reason this check exists 💀
