It seems a shame to clutter the dladm link property space (and thus dladm show-linkprop output) with this sea of related knobs when we could instead use the same syntax that dladm show-ether uses to report this information and have a single "speed-duplex" link property that takes a list -- e.g.:
dladm set-linkprop -p speed-duplex=10G-f,1G-f net0 It would also mean we wouldn't need to add a new property with every bump in speed. There's a bug logged on this: 6804384. -- meem
