This has nothing specifically to do with the proposed en-mii option, but
is rather a general issue with link properties that can have a lot of
values (such as cpus, WiFi speed, and undoubtedly others to come). We've
discussed this before in a different context (dlstat) where there was a
proposal to use the prefix "+" to add an item and "-" to remove an item.
I think a similar approach could be used with link properties -- e.g.:
* Assign en-mii to 100M-fh,10M:
# dladm set-linkprop -p en-mii=100M-fh,10M-h link1
^
* Add 100M-fh,10M to en-mii:
# dladm set-linkprop -p en-mii+=100M-fh,10M-h link1
^^
* Remove 100M-fh,10M from en-mii:
# dladm set-linkprop -p en-mii-=100M-fh,10M-h link1
^^
