Hello,

while troubleshooting an issue I was having trying to mount the root
filesystem using nfsroot running on a software emulation (solved),
I found it useful to be able to see the selected device address in the
"IP-Config: Complete" message during boot as I was troubleshooting,
and I thought it might be good in general, and a good way to try to
submit my first patch :)

The patch is against latest mainline.

Thank you for your help and comments,

Claudio Fontana
