I'm confused as to what this has to do with VMware Workstation and also ESXi.

Are you running ESXi in VMs nested on Workstation?

And cloning an instance of ESXi running in a VM to create another instance of ESXi running in a VM?

Are you aware of how ESXi networking works, with the VMkernel network interfaces essentially working like NICs? (ie. with their own MAC addresses created by the ESXi software)
