✨ mlx5dv_modify_qp_lag_port(3) ✨

okay bestie, so this one lives in the mlx5dv_modify_qp_lag_port section 3 club 💅 and it's literally about changing the lag port info on a QP. yes, that QP. let's get into it 🫶

---

🌸 NAME 🌸

mlx5dv_modify_qp_lag_port — modify the lag port information of a given QP ✨

---

🎀 SYNOPSIS 🎀

#include <infiniband/mlx5dv.h>

int mlx5dv_modify_qp_lag_port(struct ibv_qp *qp, uint8_t port_num);

---

🦋 DESCRIPTION 🦋

So this API is the moment where you get to modify the configured port num of a given QP. like, that's the whole vibe 💫

One thing tho, bestie, listen up: if the QP state gets modified later on, the port num may be implicitly re-configured. so don't come for me when it changes on its own, that's just how it is 🙈

If you wanna check the configured and active port num values, use query mlx5dv_query_qp_lag_port. it's giving "trust but verify" 🔍

---

🌈 ARGUMENTS 🌈

• qp — the ibv_qp object you're issuing the action on. the main character of this call 👑
• port_num — the port_num you wanna set for the QP. that's it, that's the value 🎯

---

⭐ RETURN VALUE ⭐

• 0 on success — slay ✨
• EOPNOTSUPP if you're not in LAG mode — sorry babe, wrong vibe check 💀
• or any other errno value on other failures. no cap, other stuff can go wrong too 😭
