Thank you for pointing out the PSARC case for libpcap integration with 
libdlpi, I was not aware of this recent initiative. The webrev will come 
in handy if I am to proceed with updating libnet to use dlpi, which is 
something I'm prepared to do if the whole ARC feels it is necessary. 
This request expands the scope of libnet's integration case compared to 
our original intentions, and I will need a firm direction from the ARC 
in order to get this work scheduled.
