💅 rtl83xx_port_bridge_leave — the Kernel API Manual, bestie edition ✨

Okay so real quick, before we get into it: this is rtl83xx_port_bridge_leave(9), and yes it's from the Kernel API Manual (very official, very demure). Lowkey obsessed already. Let's go 🎀

🌸 NAME 🌸

rtl83xx_port_bridge_leave — literally just means leave a bridge, no cap 💅

🦋 SYNOPSIS 🦋

void rtl83xx_port_bridge_leave (struct dsa_switch *ds , int port ,
       struct dsa_bridge bridge );

That's the whole vibe check right there. Void function, three args, in and out, periodt ✨

🎀 ARGUMENTS 🎀

  • ds — the DSA switch instance 💖 like, the whole switch, the main character
  • port — the port index, aka which port we're talking about, iykyk
  • bridge — the bridge being left 🫶 the one this port is walking away from

✨ DESCRIPTION ✨

Okay so picture this: a port needs to dip out of a bridge. That's the whole job, and that's what this function handles — removing a port from a bridge. 🌈

It's not just a flounce-and-leave situation though, because it also updates the port isolation masks and the EFID. Both of them. Every time. No skipping steps, bestie 🙈

🧚 CONTEXT 🧚

It can sleep. 😴 That's it, that's the note. So don't go calling it somewhere you're not allowed to catch some Zs, ok? 💀

⭐ RETURN ⭐

Nothing. Nada. It returns void — no return value, no little gift at the end. And honestly? Iconic. It did the work, it doesn't need to prove anything 👑

Note the rtl83xx_port_bridge_join(9) right there in the mix — the leave function and the join function, reunited, as they should be. 🥹
