New Revision: 323077
URL: https://svnweb.freebsd.org/changeset/base/323077

Log:
  Do not abuse flag that is clearly marked as unused.
  This creates conflicts with FreeBSD variations that may use it.  The
  usage of the flag M_TOOBIG is limited to iflib queue, thus using
  one of M_PROTO flags is fine.  There is no need to grab global flag.
