This callback doesn't seem to serve much purpose, and prevents things like: - systemd.link files from disabling autonegotiation - carrier detection in NetworkManager prior to userspace bringing the link up. The only fear I can think of is accessing unclocked resources due to pm_runtime, but ethtool ioctls handle that as of commit f32a21376573 ("ethtool: runtime-resume netdev parent before ethtool ioctl ops") Signed-off-by: Andrew Halaney <ahalaney@redhat.com> --- drivers/net/ethernet/stmicro/stmmac/stmmac_ethtool.c | 8 -------- 1 file changed, 8 deletions(-) --- base-commit: a59668a9397e7245b26e9be85d23f242ff757ae8 change-id: 20240424-stmmac-no-ethtool-begin-f306f2f1f2f4 Best regards,
