💅 i40e_ptp_set_led_hw — Set HW GPIO led

okay so bestie, welcome to the i40e_ptp_set_led_hw(9) page. this is from the Kernel API Manual, and it's literally about flipping a little LED on your network card so external clock stuff knows what's up. no cap, it's tiny but iconic.

✨ SYNOPSIS ✨

void i40e_ptp_set_led_hw (struct i40e_hw *hw , unsigned int led , enum
       i40e_ptp_led_pin_state state );

🎀 ARGUMENTS 🎀

  • hw — pointer to the hardware structure. like, the whole vibe of the card, you pass it through.
  • led — led index. which little light we're talking about, bestie.
  • state — led state. what we want that light to actually do.

🦋 DESCRIPTION 🦋

Set status of GPIO led for external clock handling.

fr fr that's the whole thing — you're telling the GPIO LED what's good so the external clock handling stays slaying. it's giving "tiny function, big responsibility" energy. 💖
