💅 t3_os_phymod_changed — the Kernel API Manual page you didn't know you needed

okay so this is a page from the Kernel API Manual and it's about one very specific little function, and honestly? She's doing her job and we love her for it. 🫶

✨ NAME ✨

t3_os_phymod_changed — handle PHY module changes

like literally what it says bestie. PHY module changes get handled. that's the whole vibe. 🦋

🌸 SYNOPSIS 🌸

void t3_os_phymod_changed (struct adapter *adap , int port_id );

that's it. that's the signature. two args, no return value, she's void and she's thriving for it. ✨

🎀 ARGUMENTS 🎀

  • adap — the adapter associated with the link change. you know, the whole adapter. the big one. 🧚
  • port_id — the port index whose limk status has changed. yes. limk. that's not me, that's the page, i'm just the messenger 💀 (iykyk)

👑 DESCRIPTION 👑

This is the OS-dependent handler for PHY module changes. It is invoked when a PHY module is removed or inserted, for any OS-specific processing.

okay let me say that again slower because it's the actual whole point: module out, module in, handler goes off. that's the entire job. if your OS wants to do something when the physical layer hardware gets swapped around, this is where it happens. it's the OS-specific part of the story, so what exactly goes down in there? depends on the OS, babe. no cap. 💅

the way that this is highkey the designated vibes-check for hot-plugged PHY modules — she ate and left no crumbs. 🌈
