[dpdk-dev] Running DPDK application with non-previlege mode

[Kamaraj P]

Thanks Bruce.

BTW we are trying to run our application as docker container.
We may need to pass the parameters(system capability) along with docker
command line to mount the hugepages ?
Like this : https://github.com/usnistgov/ndn-dpdk/blob/main/docs/Docker.md

Please share your thoughts.

Thanks,
Kamaraj
