💖 i40e_dcbnl_getdcbx(9) — the Kernel API Manual glow-up 🎀

okay so bestie, welcome to the Kernel API Manual, specifically the i40e_dcbnl_getdcbx(9) page — yes it's a mouthful, yes it's iconic, no you don't have to say it out loud at a party.

🌸 NAME 🌸

i40e_dcbnl_getdcbx — retrieve the current DCBx capability, periodt 💅

🦋 SYNOPSIS 🦋

u8 i40e_dcbnl_getdcbx(struct net_device *dev);

Like, that's it. One argument in, a u8 out. No cap, it's that simple. 💖

🎀 ARGUMENTS 🎀

• dev — the corresponding netdev, aka the network device you're asking about. That's the whole vibe check, that's the only thing it needs from you 🫶

⭐ DESCRIPTION ⭐

Returns the DCBx capability features. That's literally it — it's a getter, it goes and fetches the current DCBx capability for you and hands it back. A little fetch quest, but make it kernel. No side quests, no surprises, just ✨ capa­bility retrieval ✨. Lowkey obsessed with how clean that is.
