dpni_set_single_step_cfg(9)

✨ dpni_set_single_step_cfg(9) ✨

okay so this is a page from the Kernel API Manual, and it's all about dpni_set_single_step_cfg — the little function that turns single step PTP on or off and configures it. yes bestie, we're doing PTP things today 🕰️💅

---

🌸 NAME 🌸

dpni_set_single_step_cfg — enable/disable and configure single step PTP

---

🦋 SYNOPSIS 🦋

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

like, it returns an int, and it takes four things. that's the whole vibe. ✨

---

🎀 ARGUMENTS 🎀

• mc_io — Pointer to MC portal's I/O object. it's giving "the doorway to the management complex" energy 🚪
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. flags on flags on flags, periodt 🚩
• token — Token of DPNI object. your little DPNI hall pass, lowkey 🔑
• ptp_cfg — ptp single step configuration. the actual config, the main character of this whole function 👑

---

💀 RETURN 💀

sooo the original page literally leaves this section empty — no return value description to be found. i'm not gonna invent one for you, bestie. that's a no-cap boundary 🙈

---

🔥 DESCRIPTION 🔥

okay here's the tea ☕ — this function has effect only when the dpni object is connected to a dpmac object.

and if the dpni is not connected to a dpmac? no stress. the configuration will be stored inside and applied when the connection is made. it's giving "saving your draft until the wifi comes back" energy 😭💾
