From 2aea3c712826824dbbbaa7b9c0b70936819304b4 Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Wed, 5 Sep 2012 13:50:10 -0700 Subject: [PATCH] Tools: hv: Add an example script to retrieve dhcp state To keep the KVP daemon code free of distro specific details, we invoke an external script to retrieve the DHCP state. This is an example script that was used to test the KVP code. This script has to be implemented in a Distro specific fashion. For instance on distros that ship with Network Manager enabled, this script can be based on NM APIs. Signed-off-by: K. Y.
