I feel that if this change is needed, it should go in before 7.0 as it's 
a change in default behaviour and not a bug as such.

I've made the change in b48d4bdd2bef865c566ef645db26087737269b13 so that 
if the interface is activated by the user for dhcpcd (by default they 
all are) then RA is disabled.
