New Revision: 205759
URL: http://svn.freebsd.org/changeset/base/205759

Log:
  MFC r204807:
  
    Destroy UDP UMA zones (empty or not) upon network stack teardown
    to not leak them making UMA/vmstat -z unhappy with every stoped vnet.
    We will still leak pages (especially as zones are marked NOFREE).
