ib_find_gid(9)

🦋 ib_find_gid(9) — Kernel API Manual 🦋

Okay bestie, so this is ib_find_gid(9), and it's literally the Kernel API Manual page for the function that returns the port number and GID table index where a specified GID value occurs. Its searches only for IB link layer — the manpage literally says: Its searches only for IB link layer. No cap, that's the vibe 🔥

🎀 NAME 🎀

ib_find_gid — returns the port number and GID table index where a specified GID value occurs. Its searches only for IB link layer. Periodt 💅

---

✨ SYNOPSIS ✨

Here's the signature, bestie — keep it exactly like this:

int ib_find_gid (struct ib_device *device , union ib_gid *gid , u32
*port_num , u16 *index );

---

💖 ARGUMENTS 💖

• device — the device to query, like sliding into its DMs 💬
• gid — the GID value to search for 🔎
• port_num — the port number of the device where the GID value was found 🎯
• index — the index into the GID table where the GID was found. This parameter may be NULL — she's optional, no pressure 💅
