lowkey a reminder that this is a man page, so everything above is exactly what the kernel docs say — no invented lore, i promise 🫶

and that's the page, bestie 💜 this cutie came from source ./drivers/net/ethernet/intel/i... and it's dated October 2026, so like… future vibes but make it documentation 🌟 mwah, bye, slay 💅🎀
