shall be used.
This is not possible. The src MAC is generally a function of the ethernet PHY...
This is an editorial error that has existed since Ed1.
Perhaps this was meant to be unique per publisher device?

The terms "physical" and "logical" MAC address were coined by Digital Equipment for the PDP-11 which came with the first Ethernet cards.
"Logical" refered to the logical data link, i.e. layer 2. It is wrong to call an IP address a logical address, it is a network address.
A bridge has one MAC address which is used to address it (and ARP'ed), but each port has a port MAC address that it uses, for instance in LLDP.
To avoid confusion, we could use physical for the address that can be overwritten and hardware MAC for the "burnt-in" address.
