In order to use RDMA in Kubernetes environment with SR-IOV networking mode, two main components are required:

  1. RDMA device plugin - this plugin allows for exposing RDMA devices in a Pod
  2. SR-IOV CNI plugin - this plugin provisions VF net device in a Pod

When used in SR-IOV mode, this plugin enables SR-IOV and performs necessary configuration including setting GUID, MAC, privilege mode, and Trust mode.
The plugin also allocates the VF devices when Pods are scheduled and requested by Kubernetes framework.
