Yes, I totally missed that 
ipv6_addr_scope2type(IPV6_ADDR_MC_SCOPE(addr)) in __ipv6_addr_type(), so 
the linklocal inline probably isn't worth it since it would have to be 
something like:

static inline int ipv6_addr_scope_linklocal(const struct in6_addr *a)
{
return ((a->s6_addr32[0] & htonl(0xFFC00000)) = htonl(0xFE800000) ||
         ((a->s6_addr32[0] & htonl(0xFF000000)) = htonl(0xFF000000) &&
          ((a)->s6_addr[1] & 0x0f) = IPV6_ADDR_SCOPE_LINKLOCAL)))
}

That's not that clean an inline anymore, but still doable...

I'll clean-up the rest based on your comments and re-send.
