✨ llc_pdu_decode_ssap(9) ✨

okay bestie, gather 'round, because we are about to get intimately acquainted with a kernel API manual page. this one is lowkey a little baddie from the Kernel API Manual and honestly? it's giving "small but mighty" energy. let's get into it. 💅

🌸 NAME 🌸

llc_pdu_decode_ssap — extracts source SAP of input frame

like, that's literally her whole job. she extracts the source SAP from your input frame. no cap. 💖

🦋 SYNOPSIS 🦋

void llc_pdu_decode_ssap (struct sk_buff *skb , u8 *ssap );

there she is in all her glory. a void function, two arguments, zero drama. periodt. ✨

🎀 ARGUMENTS 🎀

• skb — the input skb that the source SAP must be extracted from. yes bestie, that's the one. hand it over. 🫶
• ssap — the source SAP, and it's an output argument, meaning she's gonna write the answer in here for you. it's giving "trust the process." 💜

🔥 DESCRIPTION 🔥

okay so here's the tea: this function extracts the source SAP of the input frame. that's the whole vibe. but WAIT — there's a little detail that makes all the difference: the right bit of SSAP is the command/response bit. so bestie, don't be out here using that bit like it's part of the address, because iykyk it is NOT. the way this is such important context and i'm obsessed. 😭👑

lowkey this is one of those "blink and you miss it" details that will absolutely humble you later, so keep it in mind fr fr.
