u32 controller , u16 pf , u16 vf , bool external );

🎀 ARGUMENTS 🎀

• devlink_port — okay so this is literally just the devlink port itself. the main character 🫶
• controller — the associated controller number for the devlink port instance. yep, that's the whole vibe ✨
• pf — the associated PCI function number for the devlink port instance 🦋
• vf — the associated PCI VF number of a PF for the devlink port instance. and listen — the VF number starts from 0 for the first PCI virtual function, no cap, that's the rule 🙈
