ipv6_addr_type() does return a mask, but there's a lot of code that just 
checks for equality since some things are mutually-exclusive - this code 
is actually identical to what ip6_route_add() does.  I don't 
particularly like this duality, but it's there - I'd gladly volunteer to 
clean this up everywhere if I didn't think there might be some 
performance reason it was done like that.

I can do that, thanks.
