💖 fcoe_ctlr_vn_lookup(9) — the Kernel API Manual moment 💖

okay so bestie, welcome to the Kernel API Manual page for fcoe_ctlr_vn_lookup — it's giving "find the VN remote port's MAC address" and honestly it's kinda iconic. let's get into it 🎀

✨ NAME ✨

fcoe_ctlr_vn_lookup — literally just: Find VN remote port's MAC address. that's the whole vibe, no notes 💅

🦋 SYNOPSIS 🦋

int fcoe_ctlr_vn_lookup (struct fcoe_ctlr *fip , u32 port_id , u8 *mac
);

yep, that's the whole thing, copied exactly, do not come for me 🙈

🌸 ARGUMENTS 🌸

  • fip — The FCoE controller. it's the main character of this whole operation 👑
  • port_id — The port_id of the remote VN_node. you gotta tell it which port you're looking for, bestie 🎀
  • mac — buffer which will hold the VN_NODE destination MAC address, if found. key words: if found. it doesn't magically appear, the buffer just holds it if the lookup slays 🔥

💜 DESCRIPTION 💜

Returns non-zero error if no remote port found. periodt. that's the entire description, and honestly? concise queen behavior ⭐ so like, if the lookup comes up empty, you're getting a non-zero error back — no cap 😭

ngl this one is short but she said what she said 💅
