i40e_get_dcb_config(9)

💖 NAME 💖

okay so welcome to the Kernel API Manual, section 9, bestie — today's main character is i40e_get_dcb_config, and honestly the original page left the name blurb totally blank, so let me just say it plain: this is the function that gets the DCB configuration from the Firmware. that's the whole vibe. 🫶

---

✨ SYNOPSIS ✨

int i40e_get_dcb_config (struct i40e_hw *hw );

like yes that's it, one function, one argument, she's lowkey minimal and I respect it 💅

---

🎀 ARGUMENTS 🎀

• hw — pointer to the hw struct. that's the one thing you gotta hand her, no cap 🦋

---

🌸 DESCRIPTION 🌸

Get DCB configuration from the Firmware.

literally that's the entire description and I'm not gonna gaslight you into thinking there's more 💀 — she goes and grabs the DCB config off the Firmware, and that is the entire job. no extra parameters, no surprise twists, no hidden lore. iconic behavior honestly, some functions could never be this concise 👑
