Section Number and Name: 

About the OpenShift SDN default CNI network provider

Describe the issue: 

OpenShift SDN provides three SDN modes for configuring the Pod network: The network policy, multitenant and subnet.

This is explained in the document [1] and also in document [2] where it is also highlighted in a Disclaimer that "Modifying the OpenShift Container Platform manifest files directly is not supported." [3].

As we know per Disclaimer in [3] and KCS [4], the supported mode is Network Policy.

The proposal is to modify the document [1] to include at least a Disclaimer explaining that the supported mode is Network Policy.
