🌸 NAME 🌸

dcb_setapp — add CEE dcb application data to app list ✨

---

✨ SYNOPSIS ✨

int dcb_setapp (struct net_device *dev , struct dcb_app *new );

---

🫶 ARGUMENTS 🫶

• dev — network interface 🖥️
• new — application data to add 🎀

💅 DESCRIPTION 💅

Heads up, bestie: Priority 0 is an invalid priority in the CEE spec. Like, literally not valid. 😭

So this routine removes applications from the app list if the priority is set to zero. That's the whole vibe check.

And the priority itself? It's expected to be an 8-bit 802.1p user priority bitmap. Periodt. 🔥
