svn commit: r186683 - head/sys/kern

[Robert Watson]

Author: rwatson

New Revision: 186683
URL: http://svn.freebsd.org/changeset/base/186683

Log:
  Temporary workaround for the limitations of the mbuf flowid field: zero
  the field in the mbuf constructors, since otherwise we have no way to
  tell if they are valid.  In the future, Kip has plans to add a flag
  specifically to indicate validity, which is the preferred model.
