DSA offers more than configuration. You can also get interface
statistics, and knowledge of if an interface is up/down. And since the
PHY of the switch becomes normal Linux PHYs, you can do cable testing,
if the PHY has support, etc.
Do you have spanning tree to break L2 network loops? Linux will
provide that as well.
However, if you are happy with dumb switch, then what you posted is
sufficient.
