10G link properties [PSARC/2009/206 Self Review]

[Peter Memishian]

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.
