Subject: [dpdk-dev] [PATCH v9 8/9] examples/guest_cli: add send policy to host
Date: Wed, 11 Oct 2017 17:18:54 +0100	[thread overview]
Message-ID: <1507738735-24879-9-git-send-email-david.hunt@intel.com> (raw)
In-Reply-To: <1507738735-24879-1-git-send-email-david.hunt@intel.com>

From: "Sexton, Rory" <rory.sexton@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"
