npftest - a tool for regression testing and debugging NPF.
It uses RUMP framework to run NPF kernel module in the userspace.

---

Test:

npfctl debug npftest.conf /tmp/npf.plist
npftest -c /tmp/npf.plist -t

Stream:

tcpdump -w stream.pcap -i $INTERFACE "host $HOST and tcp"
npfctl debug
npftest -c /tmp/npf.plist -s stream.pcap -o stream_npf_data.txt

Preferably, use MALLOC_OPTIONS="AJ" and/or other facilities.

---

Update RUMP libraries once the kernel side has been changed.  Hint:

cd src/sys/net/npf
sudo make includes

cd src/sys/rump/net/lib/libnpf
make distclean
MKDEBUG=yes MKDEBUGLIB=yes DBG="-g -O2" make -j8
sudo MKDEBUG=yes MKDEBUGLIB=yes DBG="-g -O2" make install
