I am upgrading from v2011.12 (as I have some ubifsmount issues and
don't want to debug this on an old ubi) and I saw that setting the
MAC address from EEPROM is broken.

In case there is no mac address in the environment the net/eth.c code
will set env_enetaddr to all 0. This means that is_valid_ether_addr
inside eth_getenv_enetaddr will return 0 (as of not valid). That
also means that the below function will not be called.
I assume the right fix is to change the condition to !ret.

adding %d for 'ret' would be nice.
