We need to be precises here.

DSA allows for a cluster of switches which are interconnected via
switch ports. In this setup, the Marvell switches allows ports of
different switches to be members of a trunk, which is Marvells name
for a bond/team.

The second possible setup would be multiple switch devices which are
not interconnected. Packets would then have to be forwarded from one
switch to another via the CPU when a bond/team is spread across
switches.
