30 The D in DSA stands for Distributed, because the subsystem has been designed
33 ports are referred to as "dsa" ports in DSA terminology and code. A collection
36 For each front-panel port, DSA will create specialized network devices which are
39 interfaces in DSA terminology and code.
41 The ideal case for using DSA is when an Ethernet switch supports a "switch tag"
54 Note that DSA does not currently create network interfaces for the "cpu" and
55 "dsa" ports because:
