Just because original code has an error does not make it right to 
reproduce it. :)

More seriously, heterogeneous \n placement makes it complicated to get 
and keep printing right -- for instance here the warning messages have a 
trailing \n but the code loop adds one at the end.

I would prefer that the code do a first loop (while dev!= eth_devices) 
to try and set up ethernet devices, emitting simple "warning\n" messages 
as needed, then a second loop (for dev=0 to eth_number-1) to print a 
summary of the final list of eth devices found and initialized.

Amicalement,
