💖 t4vf_update_port_info(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a kernel function page, and the whole vibe is: go ask the firmware what's up with the port, and if literally anything changed, update your notes 📝

---

🌸 NAME 🌸

t4vf_update_port_info — grab the port info and refresh it if anything's different, no cap 💅

---

✨ SYNOPSIS ✨

int t4vf_update_port_info (struct port_info *pi );

---

🎀 ARGUMENTS 🎀

• pi — the port_info 👑 like, the port's whole info situation, that's the one

---

🦋 DESCRIPTION 🦋

so here's the tea 🍓 we send a Get Port Information Command off to the Firmware, and if it comes back successful, we do a little vibe check 🔍 — we peek at whether anything is different from what we last recorded, and if it is, we update things accordingly. icon! ate! periodt 💅✨

like, no unnecessary writes, no drama, just "did anything change? okay cool, update the record" 🫶
