[En-Nut-Discussion] Still confusion about IP setup

[Christian.Schilmoeller at camco.de]

OK, concerning the ARP setup method I found out by myself that recent 
Nut/OS versions still support it if the board is booted with empty EEPROM.
It has nothing to do with NutDhcpIfConfig(), cause it still works if the 
processor is behind that initial setup function.
It seems to be implemented in the network stack, I think file net/ipin.c, 
line 208.
But I do not quite understand the reason for this setup possibility, 
because if the EEPROM reads all return 0xFF, the hardware MAC address is 
invalid, too!
Maybe it's better not to rely on the EEPROM for the MAC setup only, but 
also to include a solution that sets the MAC to a fixed, reasonable value 
from within program space ......
