>Description:

Running tests causes invalid output in net/if_ipsec/t_ipsec_natt,
in the ipsecif_natt_transport_null (and maybe others, there are multiple 
reports but this is the first occurance):

The stderr output of this test case includes garbage output from npfctl,
which prevents the html report to be generated.

>How-To-Repeat:

cd /usr/tests/net/if_ipsec/
atf-run t_ipsec_natt | hexdump -C
