  • EXT-260 Duplicate instruction error Extension
  • EXT-264 Multipart timeout errors Extension

The following extensions are partially implemented.

  • EXT-187 Flow entry notifications Extension (ONFMP_FLOW_MONITOR only)
  • EXT-232 Table synchronisation Extension (Error codes only)

The following extensions are not implemented yet.

  • EXT-191 Role Status Extension
  • EXT-192-e Flow entry eviction Extension
  • EXT-192-v Vacancy events Extension
