i40e_vc_isvalid_vector_id(9)

✨ i40e_vc_isvalid_vector_id ✨

okay so this is a page straight out of the Kernel API Manual and it's all about one tiny bool-returning vibe check, bestie. buckle up 🎀

💖 NAME 💖

i40e_vc_isvalid_vector_id — that's it, that's the name, the original page literally leaves the description blank and honestly? iconic minimalism. no cap.

---

🦋 SYNOPSIS 🦋

bool i40e_vc_isvalid_vector_id (struct i40e_vf *vf , u32 vector_id );

look at her. takes two args, gives you back a bool. simple, clean, main character energy. ✨

---

🌸 ARGUMENTS 🌸

• vf — pointer to the VF info 👑 (that's the virtual function's little info blob, if you were wondering)
• vector_id — the VF relative vector id 🎯 (relative to the VF, iykyk)

---

🌈 DESCRIPTION 🌈

the whole job: check for the valid vector id. that's literally it, fr fr. you hand her a vf and a vector_id, she tells you if that vector id is valid. no drama, no side quests, just vibes and validation 💅

lowkey reminder bestie: the description on this one is genuinely just "check for the valid vector id" — no hidden lore, no gotchas, she's a one-job icon 💀

mwah 💋 this page ships from <code>./drivers/net/ethernet/intel/i40e</code> and it's stamped <strong>October 2026</strong> — go forth and validate those vector ids, you absolute legend 👑✨
