Verify frequency attributes across nodes

  -Existing code ensures consistency of frequency data
   across all modules in istep6.12.
  -In a multi-drawer config this data needs to be
   consistent across all drawers.
  -Master drawer sends the frequency data to all the
   other via IPC mechanism.
  -This data is compared and error is returned if there
   is a mismatch.
