[PATCH v4 3/6] test: dm: add a simple unit test for DSA class

From: Alex Marginean <alexandru.marginean at nxp.com>
The test pings the local IP address though different ports of a sandbox
DSA device. Port traffic is filtered and the test verifies that ping
works only on enabled ports.
The additional interfaces require MAC addresses, these have been added
to sandbox default environment.
