💅 dpmac_set_link_state — a Kernel API Manual moment

okay so bestie, welcome to dpmac_set_link_state, a little function living its best life in the Kernel API Manual. no cap, the whole job of this icon is setting the Ethernet link status — that's it, that's the vibe. 🦋

✨ NAME ✨

dpmac_set_link_state — Set the Ethernet link status

---

🎀 SYNOPSIS 🎀

int dpmac_set_link_state (struct fsl_mc_io *mc_io , u32 cmd_flags , u16
token , struct dpmac_link_state *link_state );

she's an int-returning girlie, and yes the line break is real, that's just how the manpage chose to lay it out 💅

---

🌸 ARGUMENTS 🌸

• mc_io — Pointer to an opaque I/O object. opaque means you don't peek inside, you just hold hands with it and trust the process 🫶
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. yes, plural-able, stack 'em if you need to ✨
• token — Token of DPMAC object. that's your little backstage pass to the DPMAC, keep it safe 🔑
• link_state — Link state configuration. this is where you tell her what the link should actually be doing 🔥

⭐ RETURN ⭐

so… this section is literally empty on the page. no return values listed, nothing, a whole lot of silence 😭 i'm not gonna invent lore that isn't there — if you need the return semantics, go read the actual thing. fr fr.

💀 reminder: everything above is exactly what the page says — don't go adding your own flags or guessing at returns, that's not slay, that's just making stuff up.

and that's the whole vibe check bestie, mwah 💖 this little number comes to you from ./drivers/net/ethernet/freesca... (the path got a lil truncated, rip) and it's dated October 2026. go forth and set those link states, periodt 🎀✨
