i40e_ptp_stop(9)

💅 i40e_ptp_stop(9) — from the Kernel API Manual, bestie

okay so first things first: this is i40e_ptp_stop, and it lives in the Kernel API Manual (yes, the big one, section 9). it's a little cleanup gremlin and honestly it's giving "last one to leave the party turns off the lights" energy. 🎀

✨ NAME ✨

i40e_ptp_stop — disable the driver/hardware support and unregister the PHC 🫶

like... it packs up the support, tells the hardware bye, and takes the PHC off the registry. all in one little function. slay.

---

🌸 SYNOPSIS 🌸

void i40e_ptp_stop (struct i40e_pf *pf );

no return value, no drama. it just does the thing and dips. 💅

---

🦋 ARGUMENTS 🦋

• pf — the board private structure. that's the one and only thing you hand it, bestie. one pointer, that's the whole menu. 🍓

---

🔥 DESCRIPTION 🔥

so here's the vibe: this function handles all the cleanup work that the initialization left behind. the way that it does that is by clearing out the important information and unregistering the PHC. ✨

that's it. that's the whole job. important info: cleared. PHC: unregistered. no cap, that's literally what the manpage says and i'm not gonna invent extra steps for you. 😭

think of it as the opposite of i40e_ptp_init — the init puts stuff up, this one takes stuff down. the cleanup arc. the character development. the "okay i'm gonna head out" of kernel functions. 🙈

🧚 sign-off 🧚

this icon of a page comes straight out of ./drivers/net/ethernet/intel/i40e, dated October 2026, and it's i40e_ptp_stop(9) from the Kernel API Manual — that's the source, the version, and the date all wrapped up with a bow. 🎀

go forth, unregister that PHC, and remember: cleanup is self-care. 💖✨🌈
