__record_pdu(9)

💅 __record_pdu(9) — the linux kernel API manual, but make it make sense

okay so this one lives in the 9 section of the kernel API manual and honestly? it's a little baby function doing grown-up LACP stuff. let's get into it 🫶

---

🌸 NAME 🌸

__record_pdu — record parameters from a received lacpdu. that's it. that's the whole vibe. it takes the tea from an incoming lacpdu and writes it down 📝

---

✨ SYNOPSIS ✨

void __record_pdu (struct lacpdu *lacpdu , struct port *port );

note the void bestie — this one doesn't hand anything back. it just does the thing and dips 💅

---

🎀 ARGUMENTS 🎀

• lacpdu — the lacpdu we've received. like, the actual packet that just showed up. this is the mail, we're about to open it 📬
• port — the port we're looking at. this is the main character of the whole operation, no cap 👑

---

💖 DESCRIPTION 💖

so what does it do? it takes the parameter values for the Actor that were carried in a received lacpdu, and records them as the current partner operational parameter values. basically: whoever we just heard from is now officially our partner, and their deets go in the book 📖✨

and then, the finishing move — it sets actor_oper_port_state.defaulted to FALSE. yes queen, we are no longer defaulted. we are known. periodt 🎉
