STRUCT DEVLINK_PORT_PCI_SF_ATTRS(9)

✨ struct devlink_port_pci_sf_attrs(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for struct devlink_port_pci_sf_attrs 💅 this is the one about devlink port's PCI SF attributes, and honestly? it's giving "small struct, big responsibilities" 🎀

---

🌸 NAME 🌸

struct devlink_port_pci_sf_attrs — literally the devlink port's PCI SF attributes 💖 that's it, that's the name, no cap.

---

🦋 SYNOPSIS 🦋

here's the whole vibe, character for character, don't touch it:

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

like... four little members and they're all main characters 👑

---

🎀 Members 🎀

• controller — the associated controller number ✨ that's the whole assignment, bestie, it's u32 and it's doing its job.
• sf — the associated SF number of a PF for the devlink port instance 🌈 yes, SF number, of a PF, for the devlink port instance — every word of that matters, iykyk.
• pf — the associated PCI function number for the devlink port instance 🫶 a u16 and honestly? humble. iconic. also a PCI function number, for the devlink port instance, in case you missed it.
• external — when set, indicates if a port is for an external host controller 💀 it's a u8 bitfield with :1, so it literally only gets one bit to make its whole point. when set → external host controller. slay.

🧚 reminder: this is a struct definition, not a function — these are members, so there's no return value, no exit status, nothing to call. just vibes and fields, periodt.
