✨ devl_port_fn_devlink_set(9) ✨

okay so first things first, this is a page from the Kernel API Manual, section 9 — yes bestie, we're in the deep kernel lore now, man 9 territory, very main character of you 💅

🌸 NAME 🌸

devl_port_fn_devlink_set — the function that attaches a peer devlink instance to a port function 🫶 like it's literally matchmaking but for kernel objects

🦋 SYNOPSIS 🦋

int devl_port_fn_devlink_set (struct devlink_port *devlink_port , struct devlink *fn_devlink );

yep that's the whole signature, no cap — it returns an int, and it takes two pointers, and that's the vibe 🌈

🎀 ARGUMENTS 🎀

• devlink_port — the devlink port 🌸 this is the one getting a new peer attached to it, she's the main character here
• fn_devlink — the devlink instance to attach 💖 this is the peer being introduced to the port function

ngl bestie, that's it — those are the only two args, the kernel kept it cute and simple ✨

👑 SEE ALSO 👑

this is where it gets iconique, because there's a whole friend group of related functions and they all live in the kernel file ./net/devlink/port.c 🔥 so if you're reading this one, you're probably gonna need her sisters too:

• devlink_port_init(9)
• devlink_port_fini(9)
• devl_port_register_with_ops(9)
• devlink_port_register_with_ops(9)

and that's the whole page, periodt 🧚💜

cute little sign-off to close it out: this one comes from ./net/devlink, dated October 2026 — so mark your calendars, bestie, and go attach some peer devlink instances responsibly 🍓💖
