dpni_get_single_step_cfg(9)

💅 dpni_get_single_step_cfg — Kernel API Manual ✨

okay so bestie, welcome to dpni_get_single_step_cfg, one of the many little gems living in the Linux Kernel API Manual. The name literally tells you everything: it hands you back the current config for single step PTP. That's it. That's the whole job. no cap. 🎀

🌸 NAME 🌸

dpni_get_single_step_cfg — return current configuration for single step PTP

like, it gets the single step cfg. the vibes are immaculate and the naming is honest. 💖

---

✨ SYNOPSIS ✨

int dpni_get_single_step_cfg (struct fsl_mc_io *mc_io , u32 cmd_flags ,
u16 token , struct dpni_single_step_cfg *ptp_cfg );

she takes four things and gives you back an int. lowkey elegant. 🦋

---

🧚 ARGUMENTS 🧚

• mc_io — pointer to the MC portal's I/O object 👑 this is your entry point, your main character, the thing that actually talks to the hardware.
• cmd_flags — command flags, bestie! one or more of 'MC_CMD_FLAG_'. yes you have to pick at least one, don't leave her hanging. 🙈
• token — the token of the DPNI object. it's giving VIP wristband energy — you need it to get in. 🎟️
• ptp_cfg — the ptp single step configuration. this is where the answer lands, so like... don't pass a bad pointer, i'm begging. 😭

💀 RETURN 💀

bestie. bestie. the original page leaves this section literally empty. no documented return values, no error codes, nada. the synopsis says int and that is all the lore we get. i'm as devastated as you are. 💔

fr fr, don't go inventing return semantics — if the manpage doesn't say it, it doesn't say it. 🫶

✨ and that's the whole page, bestie! ✨

this little number ships from the source/version line ./drivers/net/ethernet/freesca... dated October 2026, and the footer keeps the same title dpni_get_single_step_cfg(9) because of course it does — consistency is a slay. 🌈🎀🫶
