🦋 i40e_chk_linearize(9) 🦋

okay bestie, welcome to the Kernel API Manual page for i40e_chk_linearize(9) — literally the vibe check for packet fragments 💅

💖 NAME 💖

i40e_chk_linearize — check if there are more than 8 fragments per packet ✨

🎀 SYNOPSIS 🎀

bool i40e_chk_linearize (struct sk_buff *skb , int count );

🌸 ARGUMENTS 🌸

• skb — the send buffer, aka the packet bestie in question 🫶
• count — number of buffers used, no cap 🧚

🔥 NOTE 🔥

So here’s the tea: 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. That’s the whole assignment, periodt 💀✨
