Subject: [dpdk-dev] [RFC 08/10] examples/guest_cli: add send policy to host
Date: Fri, 4 Aug 2017 14:54:45 +0100 [thread overview]
Message-ID: <1501854887-42427-9-git-send-email-david.hunt@intel.com> (raw)
In-Reply-To: <1501854887-42427-1-git-send-email-david.hunt@intel.com>
Here we're adding an example of setting up a policy, and allowing the
vm_cli_guest app to send it to the host using the cli command
"send_policy now"
