💅 cxgb4_port_viid — get the VI id of a port

okay so bestie, welcome to the Kernel API Manual ✨ this one is short and sweet and honestly kind of a little icon. it's cxgb4_port_viid, and it does exactly one (1) thing, and it does it flawlessly. no cap.

---

✨ SYNOPSIS ✨

unsigned int cxgb4_port_viid (const struct net_device *dev );

that's it. that's the whole vibe. one function, one arg, returns an unsigned int. slay 🎀

---

🫶 ARGUMENTS 🫶

• dev — the net device for the port. literally just hand it the struct net_device * for whichever port you're curious about and it's like "say less" 💖

---

🦋 DESCRIPTION 🦋

okay so the whole entire job here: it returns the VI id of the given port. that's the description. that's the mission. it's giving "small function, big main character energy" 👑 and honestly we love a single-responsibility queen.

no side quests, no surprises, no hidden behaviour — you give it a port, you get the VI id back. periodt. 💅

ngl the manpage is literally four lines long and I respect the confidence so much 😭
