After discussing with TX guys (cc'ed), we're re-using the udp_v6lastdst 
field. Only udp_lastdstport is added to udp_t. They're not mentioned in 
the updated PSARC material, though.

Now all hooks are added with two arguments, 'netstackid_t stack_id' and 
'void *args'. The latter can accommodate future changes to avoid 
changing the signatures again.

We'll resubmit the PSARC materials soon.
