From: javen <hidden>
Date: 2026-06-11 09:44:30
Also in: lkml
Subsystem: 8169 10/100/1000 gigabit ethernet driver, networking drivers, the rest · Maintainers: Heiner Kallweit, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

From: Javen Xu <redacted>

This patch adds current_speed in private strcut in order to decouple
