Bestie, gather round 💖 — this is tb_dp_bandwidth_mode_maximum_bandwidth(9) from the Kernel API Manual, and it's here to spill the tea on the maximum possible bandwidth. No cap.

---

🎀 NAME 🎀

tb_dp_bandwidth_mode_maximum_bandwidth — Maximum possible bandwidth 💫

---

✨ SYNOPSIS ✨

Like, the whole call looks exactly like this, bestie:

int tb_dp_bandwidth_mode_maximum_bandwidth (struct tb_tunnel *tunnel ,
       int *max_bw_rounded );

---

🦋 ARGUMENTS 🦋

• tunnel — the DP tunnel to check 👀
• max_bw_rounded — a pointer for the maximum bandwidth in Mb/s, rounded up to the next granularity ✨

---

🔥 RETURN 🔥

On success, you get the maximum possible bandwidth for this tunnel in Mb/s. On failure? Negative errno, periodt. 💅
