The fact that CPU ports can't be bridged is already not ideal.
One can have a DSA switch with cascaded switches on each port, so it
acts like N DSA masters (not as DSA links, since the taggers are
incompatible), with each switch forming its own tree. It is desirable
that the ports of the DSA switch on top are bridged, so that
forwarding between cascaded switches does not pass through the CPU.
