It doesn't seem like the right fix to me. It means if a user
enable/disable one offload in the command line they are silently
changing from the default behaviour of other offloads? I could
understand if the user set all offloads in one go through a mask but not
when they are set seemingly independent.
It looks like you need to track which ones have been enabled/disabled by
the user, and use the default for for the other offloads.
