As Andrew has already explained, DSA switch ports derive their ethernet
address from the ethernet address of the host MAC they are connected to,
and each port does not have its own ethernet address.
Please explain why you want to have DSA switch ports having their own
randomised ethernet addresses, and why this is advantageous over having
a stable ethernet address for the switch ports.

This is just a statement but gives no insight into _why_ you want this.
We want to know the reason behind this change.
