Subject: ARP response with link local IP, why not broadcast

Hello!

According to RFC3927 every ARP packet (reply and request) should be sent 
as link layer broadcast as long as the sender IP is a link local 
address. (see chapter 2.5).
That functionality would help me a lot with a use case I have with our 
application.

But it is not implemented in the kernel that way.
Does anyone know why?

Regards,
Sebastian
