RA & DHCP problem...

hey,

> Why? What problem are you solving by changing the current behavior?

We propose to decouple DHCP from RA, view them as two different 
autoconfiguration protocols. Today you can't deploy DHCP without RA and 
this forces you to support/secure two protocols that mostly overlap.

Kernel, userspace, doesn't matter but we propose not to make it 
complicated and prefer one over another. Let RA and DHCP work 
independently and configure interfaces/routing tables. Let kernel sort 
out which address/route to use based on weights or even ECMP over both 
RA and DHCP defaultroutes if one chooses to do so.
