Notes :

1. AirInterfacePowerSaver(AIPS) v0.0.5 consumes the APIs in the MicroWaveDeviceInventory(MWDI) v1.1.0 application.
   In the latest MWDI’s tag test_v1.1.2 the required support is not there.
   Please find the details here , openBackhaul/MicroWaveDeviceInventory#509
   So AIPS development team tested AIPS application with dummy data.
   Once the APIs are ready in the MWDI application , end-to-end testing will be done.

2. For the open issue, for now we compared the transmission-mode-cur and transmission-mode-max within the same endpoint. For example link-id-B-endpoint-1/transmission-mode-cur == link-id-B-endpoint-1/transmission-mode-max.

3. For the open issue, for now we are fetching the operation-key of the operation-server as response-receive-operation is present as operation-server . This will be changed once the specification is changed as per comment #114 (comment)
