ice_chk_linearize(9)

✨ NAME ✨

okay so bestie, this page is ice_chk_linearize(9) from the Kernel API Manual — the little function that checks if there are more than 8 fragments per packet. 💅

ice_chk_linearize — Check if there are more than 8 fragments per packet.

🌸 SYNOPSIS 🌸

bool ice_chk_linearize (struct sk_buff *skb , unsigned int count );

🎀 ARGUMENTS 🎀

• skb — send buffer. the packet’s send-buffer bestie 🫶
• count — number of buffers used. literally how many buffers are in play ✨

💀 NOTE 💀

heads up, bestie: 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. 😭
