Enable the plugin to override the base DHCP DeviceManager.
This patch does the following:
1. provide a class that overrides the default. This is required
so that we can override the device_manager class
2. Introduces two new configuration variables:
- dhcp_override_mac - enables the driver to override the
neutron port mac address. This should be used when the DHCP
agent is running on a VM that is connected to the DVS. This
can save the admin the bother of setting 'forged transmits'
to enable. This should be the MAC address of the VM
- dvs_integration_bridge - the name of the bridge to plug the
interface. This may be a dedicated bride that is connected
to the DVS
This enables one to use the simple DVS plugin and actaully get a
DHCP address.
NOTE: a port group that can see all of the tags should be
configured. This is the port group that the dvs_integration_bridge
should be attached to.
