I have a dirty workaround for it.
Edit the file:
/etc/network/interfaces
Add a line with a mac:
hwaddress ether AA:BB:CC:DD:EE:FF
In my case is something like:
# Ethernet
allow-hotplug eth0
iface eth0 inet dhcp
address 192.168.8.100
netmask 255.255.255.0
gateway 192.168.8.1
hwaddress ether 02:03:46:C1:5F:E6
And that’s it.
