Subject: net: Print error message upon net usage when no ethernet-interface is found
X-Git-Tag: v1.3.2~19^2

net: Print error message upon net usage when no ethernet-interface is found

This patch fixes a problem seen on PPC4xx boards, when no MAC address is
defined. Then no ethernet interface is available but a simple "tftp"
command will return without any error message which is quite confusing.
