Tested these platforms:

Solaris 8 -> sends src IP address of INTERFACE
Cisco -> sends src IP address of INTERFACE
Windows 2000, XP -> sends src IP address of INTERFACE
Linux 2.6.0-pre1, 2.4.20, 2.4.21 -> sends src IP address of LOOPBACK

Question: ¿What would be the implications of applying my patch or similar to do linux behave like other OS?

Same tests:

Solaris 8 -> replies the ARP request
Windows 2000, XP -> replies the ARP request
Linux 2.4.21 -> replies the ARP request
Cisco -> NOT replies the ARP request

I will contact Cisco to see why they don't do and if it can be fixed in future releases.
