The thought was to enable all ports to the maximum supported by default. This
was the behavior before this option was added so it was though to leave it
alone by default.

Is there a reason this should not happen? I guess since the Volume 2 spec
says that the power on default for this is LinkSpeedSupported there is no
reason to have the SM send these Set's. Perhaps there is broken hardware out
there?
