This looks very similar to an issue that got patched on the i.MX6 yesterday
by Stefano which said:

commit fd3056337e6fcc140f400e11edd33f6f1cb37de1
"Use env callbacks for net variables" has a side effect on i.MX6 boards
because they do not set CONFIG_NET: the ip address results not set, but it
is stored in the environment."

Might be something to check...

Regards,

Andy.
