- flow cookie [64b] is present at receivedPacket (to distinguish responsible flow)
- connection cookie [32b] is present at receivedPacket and is expected
  to be copied into corresponding transmitPacketInput (to distinguish auxiliary connection)
- offtopic: felix generated META-INF moved to target (drop-test, test-provider)
- hotfix - InstanceIdentifier API changes adaptation
