💅 ice_set_dcb_cfg — bestie's guide to pushing DCB config at the firmware

okay so real talk, we're in the ice kernel API manual today — yes, the ice_set_dcb_cfg(9) page, the one your boomer coworker keeps tabbing to at 2am. grab a strawberry drink 🍓 and let's go, because this one is short but she's important.

---

✨ NAME ✨

ice_set_dcb_cfg — push the local LLDP MIB straight to the FW, no cap 💅

(yes "FW" means firmware. we abbreviate here. it's giving efficiency.)

---

🌸 SYNOPSIS 🌸

int ice_set_dcb_cfg (struct ice_port_info *pi );

like, that's it. one function, one arg, returns an int. she's lowkey minimal. 🎀

---

🦋 ARGUMENTS 🦋

• pi — the port information structure 🫶. that's your port's whole little identity card, and yeah she's a struct ice_port_info *. main character energy, honestly.

---

💖 DESCRIPTION 💖

so what does she do? she sets the DCB configuration to the Firmware. that's the whole vibe. ✨

like — DCB config goes in, firmware gets told about it, and that's the moment. no dramatic monologue, no extra steps listed, that's literally the documented behaviour. periodt. 👑

that's the whole page, bestie — short, sweet, and she said everything she needed to say. 🌈

and for the cute sign-off: this little gem lives over at ./drivers/net/ethernet/intel/ice, she's dated October 2026, and she goes by ice_set_dcb_cfg(9) — stan her, she's doing her best 🧚💜✨
