New Revision: 355142
URL: https://svnweb.freebsd.org/changeset/base/355142

Log:
  Move ipf_pcksum6() to its rightful place, in ip_fil_freebsd.c. This
  FreeBSD-only function should live in the O/S specific source file.
  
  This essentially reverts r349929 Now that ipftest and ipfreplay are
  disabled in FreeBSD 11-stable.
  
  MFC after:	3 days
