that's the whole signature, character for character, don't come for me 🫶

🦋 ARGUMENTS 🦋

• fman — a pointer to the FMan device 💖 like, the actual FMan struct, hand it over
• port_id — the port id 🎀 yes that's it, that's the whole parameter. short and iconic

🔥 DESCRIPTION 🔥

okay so what does it do: it gets the QMan channel ID associated to the port id 👑

you give it a port id, it gives you back the matching QMan channel ID. that's the vibe check and it passes ✨ no hidden lore, no extra steps, it's giving one-job-wonder and honestly? obsessed.
