ice_stop_phy_timer_e82x(9)

💅 ice_stop_phy_timer_e82x — stop the PHY clock timer

ok so bestie, gather round, because this one is from the Kernel API Manual and it's literally the "cut the music" function for a PHY port's clock 🎀

---

✨ NAME ✨

ice_stop_phy_timer_e82x — Stop the PHY clock timer ⏱️✋

---

🦋 SYNOPSIS 🦋

int ice_stop_phy_timer_e82x (struct ice_hw *hw , u8 port , bool
soft_reset );

---

🌸 ARGUMENTS 🌸

• hw — pointer to the HW struct 🫶 (yes the classic, you know her)
• port — the PHY port to stop, like, the actual one you're shutting down 👑
• soft_reset — if true, hold the SOFT_RESET bit of P_REG_PS 💀 (yes literally hold it, don't let go)

---

💖 DESCRIPTION 💖

Stop the clock of a PHY port. That's the whole vibe. ⏰🚫

But listen — you can't just do this whenever, okay? This must be done as part of the flow to re-calibrate Tx and Rx timestamping offsets whenever the clock time is initialized, or when the link speed changes. It's giving "required step in the ritual" energy, no cap. 🔥

bestie pls don't skip it, it's not optional, it's the whole point 🙈
