 This document describes functional behavior of the CMIS application initialization support in SONiC.
 
 The Common Management Interface Specification (CMIS) provides a variety of features

-CMIS transceiver may support multiple application, and the application initialization sequence is now mandatory for the dynamic port breakout mode to correctly update the active CMIS application based on the desired port mode. Otherwise the link will be down if the host port mode does not match the selected application on the CMIS transceiver.

 The feature is built on top of SONiC **sfp-refactor** framework to provide a platform-independent
 solution, and the individual platforms could easily enable this feaure by having its **Sfp** inherited from **SfpOptoeBase**.
