ice_get_num_vfs(9)

💖 ice_get_num_vfs(9) 💖

okay so bestie, welcome to the ice_get_num_vfs page from the Kernel API Manual ✨ — it's short, it's sweet, and it will absolutely humble you if you skip the one warning in it. let's go 🫶

---

✨ NAME ✨

ice_get_num_vfs — get the number of allocated VFs 💅

---

🎀 SYNOPSIS 🎀

u16 ice_get_num_vfs (struct ice_pf *pf );

literally one argument, one return value, no drama 🌸

---

🦋 ARGUMENTS 🦋

• pf — the PF private structure. that's it, that's the whole argument list, she's low maintenance 👑

---

🌈 DESCRIPTION 🌈

so the function returns the total number of allocated VFs. simple, right? right. 🎯

⚠️ NOTE, and please actually read this one bestie ⚠️ VF IDs are not guaranteed to be contiguous. do not assume that a VF ID is guaranteed to be less than the output of this function. like, do not do that. i'm begging you 😭 that assumption is not the vibe, it's giving undefined-behavior-adjacent chaos 💀

so: count ≠ ID. the count is a count, the IDs are their own little chaotic selves 🧚✨
