Open Stack

Hello,
By default the networking-ovs-dpdk plugin will download the ovs branch and tag specified in its default settings in the local.conf:
" enable_plugin networking-ovs-dpdk https://github.com/openstack/networking-ovs-dpdk master "

Question:
How to  override this  in the  local.conf and to specify a path to my private version of ovs-dpdk ? 
I understand that the path  should be specified in a manner that is compatible with git clone command. How ?

Regards avi
