"Switch" and "DSA master" are not interchangeable concepts. A DSA master
is a regular Ethernet controller that is connected to a local (onboard
or embedded) switch and handles its management traffic. The use of the
term has existed since the introduction of DSA in 2008 and has reached a
wide audience among users through the papers that popularized DSA later, mainly
https://legacy.netdevconf.info/2.1/papers/distributed-switch-architecture.pdf
Whereas a switch is a multi-port Ethernet device that handles L2
forwarding by MAC DA and VLAN ID, essentially containing a hardware
implementation of the Linux bridge.
