Atop command run inside docker shows network speed as 0 Mbps

I parse atop inside my Java application to get system load, network speed and so forth. Recently I started deploying my app using docker containers. When I ssh in to the docker and run the atop, I notice (shown on attached image) atop shows sp 0 Mbps which suppose to show sp 1000 Mbps.

I started the container with --privileged and all the containers runs on its own network that was created by docker network create xconvert-net. Is there anything I can do to allow containers to see the correct network link speed?
