✨ NAME ✨

pci_epf_remove_vepf — remove a virtual EP function from a physical EP function 🌸

like. that's literally the whole thing. the name ate and left no crumbs.

---

🦋 SYNOPSIS 🦋

void pci_epf_remove_vepf (struct pci_epf *epf_pf , struct pci_epf *epf_vf );

that's the whole signature, no cap. returns void — so don't be out here looking for a return value, she simply does not have one 💀

---

💜 ARGUMENTS 💜

• epf_pf — the physical EP function, aka the one the virtual EP function is getting yeeted from. she's the main character here, the one who stays 🫶
• epf_vf — the virtual EP function, aka the one being removed. bye bestie, love you, this is goodbye 😭

---

🌈 DESCRIPTION 🌈

so the whole vibe: you invoke this to remove a virtual endpoint function from the physical endpoint function. that's it, that's the tea ☕

it's the un-invite. the "we need to talk." the removal of the vf from the pf. iconic behavior honestly 👑
