saw your this email after I hit send on the series. Since the new 
function pointer will be exactly similar to ipv6_dst_lookup
with just an additional argument, a new function pointer does not seem 
necessary. But i can certainly change it
to a new function pointer and resend if that is more acceptable.

ok, will look.
