GNOME Bugzilla – Bug 736909
Ethernet: please add ability to specify capabilities to advertise.

(initially reported at https://bugs.kde.org/show_bug.cgi?id=338881) When configuring a wired ethernet connection, networkmanagemer already offers to specify whether autonegotiation should be performed, and if not, the specific configuration (speed, duplex) to use. It is currently possible (at least with ethtool [0] - see "advertise") to keep autonegotiation on, but to limit to specific speed. This capability isn't available in networkmanager. Use-case: in a home setup with a single computer and a single handheld device that never talk to each other, gigabit ethernet doesn't provide any performance gain, but has a real (even if marginal) energy cost. My ideal scenario (that I currently achieve through modifications to the ifup script) is to have autonegotiation ON and advertise capability 0x00F (i.e. all variants of 10 and 100 mbps). Thanks!

bugzilla.gnome.org is being shut down in favor of a GitLab instance. We are closing all old bug reports and feature requests in GNOME Bugzilla which have not seen updates for a long time. If you still use NetworkManager and if you still see this bug / want this feature in a recent and supported version of NetworkManager, then please feel free to report it at https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/ Thank you for creating this report and we are sorry it could not be implemented (workforce and time is unfortunately limited).
