Reason for change:
CPE returns 9003 Invalid Arguments or returns entire parameter tree when ACS sends GetParameterNames with empty string and NextLevel true, which violates TR-069 specification
Test Procedure:

  1. connect to acs
  2. ACS sends GetParameterNames RPC with empty string ParameterNames (top of hierarchy) and NextLevel set to true
  3. check CPE returns GetParameterNamesResponse with only immediate children of top level, not entire parameter tree

Risks: Low
