fcoe_ctlr_link_down(9)

🌸 NAME 🌸

okay so welcome to fcoe_ctlr_link_down(9) from the Kernel API Manual, bestie 💖 this one is short, sweet, and lowkey iconic:

fcoe_ctlr_link_down — Stop a FCoE controller

✨ SYNOPSIS ✨

like, here’s the signature exactly as it is, no edits, periodt:

int fcoe_ctlr_link_down (struct fcoe_ctlr *fip );

🎀 ARGUMENTS 🎀

• fip — The FCoE controller to be stopped. yeah, that’s the main character getting stopped, bestie 🛑✨

💅 DESCRIPTION 💅

Returns non-zero if the link was up and now isn’t. That’s the whole return vibe — non-zero means “yep, it was up before and now it’s not” 😭.

Called from the LLD when the network link is not ready. And heads up: there may be multiple calls while the link is down — fr fr, it’s not a one-time thing, so don’t be shook 🫶.
