#Clone asfvolt16-driver
#    - The guide assumes that the asfvolt16-driver gerrit repo is cloned under the ONL toplevel directory:
#    - git clone ssh://user@gerrit.opencord.org:29418/asfvolt16-driver ${HOME}/OpenNetworkLinux/asfvolt16-driver

#git clone https://gerrit.opencord.org/${ASFVOLT_REPO_NAME} ${ONL_TOPDIR}/${ASFVOLT_REPO_NAME}

#steps to install grpc
#   - Download as zip "grpc", "grpc-c", "protobuf" and "protobuf-c" from "https://github.com/opennetworkinglab/asfvolt16-driver/tree/master/third_party"
#comment the below 4 lines and download manually in case of errors
