lowkey the most important part: this page lives in ./include/linux, it's dated October 2026, and it's brought to you under the ethtool_lin...ro_link_mode(9) name in the Kernel API Manual — so like, cite it right when you quote it bestie 🧚

and that's the page!! go forth and zero those masks, you're gonna slay 💅💖🌈
