i40e_led_get_phy(9)

💅 i40e_led_get_phy(9)

okay so welcome to the Kernel API Manual, section 9 — yes that's the kernel-developer-pages girlies, we're in the driver guts now 🫶

---

✨ NAME ✨

i40e_led_get_phy — return current on/off mode 🎀

like, literally it tells you if the LED is on or off rn. that's the whole vibe check.

---

🌸 SYNOPSIS 🌸

int i40e_led_get_phy (struct i40e_hw *hw , u16 *led_addr , u16 *val );

---

🦋 ARGUMENTS 🦋

• hw — pointer to the hw struct 💖 this is the hardware struct, she's the main character, everything goes through her
• led_addr — address of led register to use ✨ the register address for the LED we're poking at
• val — original value of register to use 🌸 the og value sitting in that register

---

💀 SEE ALSO 💀

first up, the actual kernel file this lives in — she's local, she's iconic:

./drivers/net/ethernet/intel/i40e/i40e_common.c

and then. bestie. and then there's the list. every single one of these is part of the i40e family, no cap, no skips, i'm not leaving a single one out because that would be disrespectful to the group chat 😭
