🌸 i40e_dcbnl_getnumtcs — kernel API manual, bestie edition 🌸

okay so this is a page straight out of the Kernel API Manual, and honestly? it's a tiny little function with main character energy. sit down, grab a lil snack 🍓, and let's get into it.

---

✨ NAME ✨

i40e_dcbnl_getnumtcs — literally just: get the max number of traffic classes supported 💅

---

🦋 SYNOPSIS 🦋

int i40e_dcbnl_getnumtcs (struct net_device *netdev , int tcid , u8 *num
);

---

🎀 ARGUMENTS 🎀

• netdev — the corresponding netdev, aka the net device we're talking about 🫶
• tcid — the TC id, the traffic class id in question
• num — total number of TCs supported by the device 👑

---

💖 DESCRIPTION 💖

Return the total number of TCs supported by the adapter. that's it. that's the whole vibe. no cap, it's a getter — it goes and fetches the number, and hands it back to you via num. iconique, honestly ✨
