✨ NAME ✨

llc_pdu_init_as_xid_rsp — the glow-up that builds an XID response PDU 💅

(also loml, this is from the Kernel API Manual, manual section 9, if you were wondering 🫶)

🌸 SYNOPSIS 🌸

void llc_pdu_init_as_xid_rsp (struct sk_buff *skb , u8 svcs_supported ,
u8 rx_window );

no cap, that's the whole signature. returns nothing, takes three things. iconic behaviour honestly 💖

🎀 ARGUMENTS 🎀

  • skb — the address of the skb you're about to build. like, the actual frame-in-progress bestie, hand it over 🫴
  • svcs_supported — the class of the LLC — and the class is either I or II. that's it, those are the two vibes 🌈
  • rx_window — the size of the receive window of the LLC. how much room we're leaving in the inbox, basically 📥

🦋 DESCRIPTION 🦋

okay so real talk: this function builds a pdu frame as an XID response. that's the whole arc. you give it the skb, it does the thing, XID response go brrr ✨

no extra lore, no secret side quests — it's a builder, that's the job, and it ate 💀👑
