This was an issue in Kconfig. Now with the new mv88e6xxx driver properly selected I get:

Fabio,
Looks like this is coming from net/eth-uclass.c with CONFIG_NET_RANDOM_ETHADDR not defined and would be because there is no ethaddr env to set the MAC addr?
If I undefine ethaddr on my board and define CONFIG_NET_RANDOM_ETHADDR=y I get an random MAC that is the same for all ports and DHCP/networking works but if I then disable CONFIG_NET_RANDOM_ETHADDR I see the same behavior as you - so it looks like the lack of a valid MAC addr causes eth_post_probe() to fail by design?
