✨ ksz_dcb_init — the DCB glow-up for your KSZ switch ✨

Okay bestie, welcome to the ksz_dcb_init(9) page, straight out of the Kernel API Manual 💅 This is the lil function that gets your KSZ switch's DCB configuration looking cute before anything else happens. Let's get into it 🎀

💖 SYNOPSIS 💖

int ksz_dcb_init(struct ksz_device *dev);

🦋 ARGUMENTS 🦋

• dev — Pointer to the KSZ switch device structure, aka the switch you're about to makeover 🫶

🌸 DESCRIPTION 🌸

So here's the tea ☕: this function initializes the DCB configuration for a KSZ switch. The global DSCP-to-priority mapping table gets initialized. That's the whole vibe — it's giving "setting up the group chat before anyone can send messages" ✨

⭐ RETURN ⭐

Returns 0 on success, or a negative error code on failure 😭 (so like, always check the return value, no cap).
