llc_conn_res...i_pdu_as_rsp(9)

💅 llc_conn_resend_i_pdu_as_rsp(9)

okay so this is a page straight out of the Kernel API Manual, and it's about one very specific little function, bestie. buckle up 🎀

---

✨ NAME ✨

llc_conn_resend_i_pdu_as_rsp — literally resend all unacknowledged I PDUs. that's the whole vibe. no cap. 🦋

---

🌸 SYNOPSIS 🌸

void llc_conn_resend_i_pdu_as_rsp (struct sock *sk , u8 nr , u8
first_f_bit );

it returns void, so like… it gives nothing back. it just does the thing. honestly iconic behavior 💅

---

🫶 ARGUMENTS 🫶

• sk — the active connection. the main character of this whole operation 🔥
• nr — the NR. yes that's it, that's the description, the manpage is being mysterious and honestly? i respect it 🙈
• first_f_bit — the f_bit value of the first pdu. so it's the F-bit flavor for pdu numero uno ✨

---

💖 DESCRIPTION 💖

so here's the tea, bestie: this function resends all the unacknowledged I PDUs, starting with the NR. 🫶

the first one goes out as a response PDU with the F bit equal to first_f_bit. so like, you hand it the vibe you want and it delivers ⭐

and if there's more than one to send? the subsequent ones go out as response PDUs with the F bit equal to zero (0). periodt. the rest of them are all zero-F-bit girlies. 🎀

real talk: the first PDU gets your first_f_bit, everything after that gets 0. don't mix that up 👑
