ixgbe_led_off_t_x550em(9)

👑 NAME 👑

okay so this page is ixgbe_led_off_t_x550em(9) from the Kernel API Manual, and bestie… it does exactly what it says on the tin: it turns off the software controllable LEDs. that's it. that's the whole gig. the little blinky lights on your NIC? this function is the one that says "lights out, babe" 💡➡️🌑 and honestly? iconic behavior. no cap.

✨ SYNOPSIS ✨

int ixgbe_led_off_t_x550em (struct ixgbe_hw *hw , u32 led_idx );

literally the whole signature, copied exactly character for character, spaces before the commas and all — don't @ me, that's how the original rolls 🫶

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. it's giving "here's the actual NIC, go talk to it" energy. you hand over the struct, the function does the rest 💅
• led_idx — led number to turn off. yes, which one. there's more than one LED possible, bestie, so you gotta be specific. this is the "pick your fighter" part of the process 🌸

🦋 SEE ALSO 🦋

okay this list is long long. the original drops sixty cross-references on you and I am NOT about to skip a single one, because every single one is part of the family. go read them. all of them. think of it as a group chat you were just added to 👑

also worth shouting out: this whole thing lives in the kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_x550.c 📁

🌈 the sign-off 🌈

bestie you made it to the bottom, I'm so proud 😭 this page comes to you sourced from ./drivers/net/ethernet/intel/i... (yes, it's literally truncated in the original — that's not me being lazy, that's the actual footer, keep it) and dated October 2026, all under the title ixgbe_led_off_t_x550em(9). go forth, turn those LEDs off, and slay 💖✨🎀
