dpmac_set_protocol(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 dpmac_set_protocol(9) — ok bestie, let's talk DPMAC

So this is a page from the Kernel API Manual, and it's all about dpmac_set_protocol — one little function whose whole entire job is reconfiguring the DPMAC protocol. That's it. That's the vibe. ✨

✨ NAME ✨

dpmac_set_protocol — literally just "Reconfigure the DPMAC protocol". Iconic, concise, no notes. 💅

🎀 SYNOPSIS 🎀

int dpmac_set_protocol (struct fsl_mc_io *mc_io , u32 cmd_flags , u16
token , enum dpmac_eth_if protocol );

Like… copy that exactly, okay? Don't retype it from memory, I beg you. 😭

💖 ARGUMENTS 💖

  • mc_io — a pointer to the opaque I/O object. Lowkey the mystery box of the group chat; you don't look inside, you just pass it along. 🫶
  • cmd_flags — the command flags, and bestie they're one or more of 'MC_CMD_FLAG_'. Yes, that's the actual name in quotes. Yes, you keep the quotes. 🎀
  • token — the token of the DPMAC object. It's your little hall pass for this specific DPMAC, iykyk. 🦋
  • protocol — the new protocol you want the DPMAC reconfigured into. It's typed as enum dpmac_eth_if, so slay, but keep it in the enum. ⭐

🌸 RETURN 🌸

The original genuinely doesn't say anything under RETURN — no description, no values, nothing. So I'm not out here making stuff up for you, bestie. 🙈 Empty section is empty. Not me inventing exit codes. Periodt.

🌈 SEE ALSO 🌈

Kernel file — the one and only:

./drivers/net/ethernet/freescale/dpaa2/dpmac.c

And the whole DPMAC friend group, go say hi to all of them 👑:

Lowkey reminder: everything literal here — the function signature, the 'MC_CMD_FLAG_' bit, the file path, all the (9) cross-refs — stays exactly as written. Cute font, same facts. That's the whole assignment. 💜

Okay that's the whole page, go be a main character with your DPMAC reconfiguration. 🧚 This little cutie came straight out of ./drivers/net/ethernet/freesca... (the footer truncated it like that, so that's how we're leaving it, no editing bestie), dated October 2026, and it signs off as dpmac_set_protocol(9) — same as it started, full circle, obsessed. 🍓🔥
