I came across (after guesses :) __FreeBSD__ and now have sendfile()
support that appears to work.
# ./netperf -c 617730 -t TCP_STREAM -H 192.168.1.67 -l 20 -- -s 128K -S
128K -m 32K

and then sendfile:
# ./netperf -F ./netperf -c 617730 -t TCP_SENDFILE -H 192.168.1.67 -l 20
-- -s 128K -S 128K -m 32K

this will be part of 2.2pl4. for those anxious to have it now, here are
the diffs:
