New Revision: 216837
URL: http://svn.freebsd.org/changeset/base/216837

Log:
  MFC r216049:
  Some drivers rely on the existence of certain keys. The Atheros 9xxx
  driver for example requests the NetCfgInstanceId but doesn't check the
  returned status code and will happily access random memory instead.
