llc_pdu_decode_dsap(9)

okay so bestie, welcome to the llc_pdu_decode_dsap(9) page from the Kernel API Manual 💅 this function has one tiny job and she is doing it with main character energy ✨

🎀 NAME 🎀

llc_pdu_decode_dsap — extracts dest SAP of input frame. That's the mission, no cap 🫶

✨ SYNOPSIS ✨

void llc_pdu_decode_dsap (struct sk_buff *skb , u8 *dsap );

💖 ARGUMENTS 💖

• skb — input skb that destination SAP must be extracted from it. Yep, this is the input skb the destination SAP comes out of 💅
• dsap — destination SAP (output argument). She's the output argument, so the extracted destination SAP lands here 🎀

🦋 DESCRIPTION 🦋

This function extracts destination SAP of input frame. Simple, iconic, focused — it's giving very targeted little helper energy 💖

Also important: the right bit of DSAP designates individual/group SAP. Keep that in mind, bestie — that right bit is lowkey doing important labeling work 👑
