ice_cpi_ena_dis_clk_ref(9)

💅 ice_cpi_ena_dis_clk_ref — a whole vibe (from the Kernel API Manual, bestie)

okay so picture this: you're deep in the ice driver, you've got a PHY, you've got a Tx reference clock, and you just need it on or off. that's the whole plot. this function is the girly who handles it. ✨

---

✨ SYNOPSIS ✨

int ice_cpi_ena_dis_clk_ref (struct ice_hw *hw , u8 phy , enum
ice_e825c_ref_clk clk , bool enable );

like, that's literally it. four things in, one int out. she's simple, she's iconic, she serves. 🎀

---

🌸 ARGUMENTS 🌸

• hw — pointer to the HW struct. the main character. everything runs through her. 👑
• phy — the phy index of the port whose Tx reference clock you're enabling or disabling. which port? this port, bestie. 🦋
• clk — the Tx reference clock you wanna enable or disable. type is enum ice_e825c_ref_clk, so pick from the menu, don't freestyle. 🍓
• enable — bool value to enable or disable the Tx reference clock. true = on, false = off. the whole duality of woman, honestly. 💅

---

🔥 DESCRIPTION 🔥

so what does she actually do? this function executes a CPI request to enable or disable a specific Tx reference clock on the given PHY. that's the tea. no extra steps, no surprises, she just sends the request and minds her business. periodt. 💖

---

⭐ RETURN ⭐

• 0 on success 🎉
• negative error code on failure 😭

ngl, always check the return value. she will tell you when things went sideways, and ignoring her is not the flex you think it is. 🙈
