mlx5_ib_get_counters_id(9)

💅 mlx5_ib_get_counters_id — a kernel API manual, but make it cute ✨

okay bestie, so this one's from the Kernel API Manual, section 9 (the kernel dev pages, iykyk 🧚). It's short, it's sweet, and it's literally just one function doing one little job. Let's get into it 🎀

✨ NAME ✨

mlx5_ib_get_counters_id — returns the counters id you should use for a given device + port combo 🦋

---

🌸 SYNOPSIS 🌸

u16 mlx5_ib_get_counters_id (struct mlx5_ib_dev *dev , u32 port_num );

that's it. that's the whole call. no cap 💅

---

💖 ARGUMENTS 💖

• dev — a pointer to the mlx5 IB device 🫶 like, the actual device struct, pointed at.
• port_num — the port number, and bestie listen, it's zero based. zero based!! so port 0 is the first one, not port 1. don't do a me and forget 🙈

---

🔥 DESCRIPTION 🔥

so mlx5_ib_get_counters_id returns the counters set id to use for the given device-port combination, and it works in both switchdev and non switchdev mode of the parent device 👑

that's the whole vibe. you hand it a device and a port, it hands you back the counters id. main character energy honestly 🌈
