STRUCT DEVLINK_PORT_PCI_PF_ATTRS(9)

💅 struct devlink_port_pci_pf_attrs(9)

okay so bestie, we're in the Kernel API Manual and this page is literally all about struct devlink_port_pci_pf_attrs — the devlink port's PCI PF attributes, no cap. it's giving "small struct, big job" energy and honestly? iconic. 🎀

---

✨ NAME ✨

struct devlink_port_pci_pf_attrs — the devlink port's PCI PF attributes, periodt. 💖

---

🦋 SYNOPSIS 🦋

struct devlink_port_pci_pf_attrs {
    u32 controller;
    u16 pf;
    u8 external:1;
 };

look at her. three members, one lil bitfield, flawless. 🌸

---

👑 Members 👑

• controller — the associated controller number. it's the controller she's rolling with, okay?! 🫶
• pf — the associated PCI function number for the devlink port instance. yes, that PF. the one your port instance is attached to. 💅
• external — when this is set, it indicates if a port is for an external host controller. it's a single bit and it's carrying a whole lot of "wait, is this port for an external host controller?" on its tiny u8 external:1 shoulders. 😭👑

heads up bestie: if you actually go touch this in real life, the source of truth is that kernel file ./include/net/devlink.h — always check there, iykyk. 💀
