as other said, there is no negative argument but it does not
seem worthwhile, because at least with current packet rates
you should be able to extract packets using pcap.
Unless, of course, you are running a 300Mbit/s interface
on a slow embedded CPU, in which case the efficiency of
netmap might be helpful.
