dpni_enable(9)

💖 NAME

Okay so bestie, gather round: dpni_enable — it's the function that enables the DPNI and lets it send and receive frames. That's it. That's the whole vibe. It's giving "flip the switch, we're live" energy 🔥

This page lives in the Kernel API Manual section (section 9, for the uninitiated) — so yes, it's a kernel function, not a command you type into your shell, don't @ me.

---

✨ SYNOPSIS

int dpni_enable (struct fsl_mc_io *mc_io , u32 cmd_flags , u16 token );

Three args, one int coming back at you. Short, sweet, iconic. 💅

---

🎀 ARGUMENTS

• mc_io — Pointer to the MC portal's I/O object. Like, the actual connection handle you're working through, bestie 🫶
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. Yes, that's literally the family name it gives you — pick from that crew 🌈
• token — Token of the DPNI object. This is how you tell it which DPNI you mean 🎯

---

🦋 RETURN

Not me showing up to this section and it's literally empty 😭😭 No documented return values here — nothing to report, no cap. So don't come for me asking what it returns, the manual kept it a mystery 🙈

Reminder bestie: that SEE ALSO list is long enough to be its own friend group, but every single one is there — no gatekeeping, no cuts 💖

And that's a wrap, babes 🎀 This cutie came from ./drivers/net/ethernet/freesca... and it's dated October 2026 — so yeah, fresh off the press, and it's still called dpni_enable(9). Slay. ✨💅🦋
