To support multi-tenant networking in Ironic we need to be able to discover not just the NICs a baremetal machine has but also the physical connectivity to switches in the network. This patch collects LLDP (Link Layer Discovery Protocol) data as part of the list interfaces stage of the generic hardware manager. This information can then be processed by the ironic inspector to populate the local link information on each ironic port. The processing done on this data in ironic python agent is limited, this is to allow for server side processing hooks to process as much or as little of the data as they want. This is to allow for multi-vendor environments that might use different parts of the LLDP packet to use a generic ramdisk and configure the processing server side using inspector plugins. Reserved fields switch_port_descr and switch_chassis_descr have been deprecated for removal in Ocata in favor of passing the whole packet.

ironic-python-agent
An agent for controlling and deploying Ironic controlled baremetal nodes.
The ironic-python-agent works with the agent driver in Ironic to provision the node. Starting with ironic-python-agent running on a ramdisk on the unprovisioned node, Ironic makes API calls to ironic-python-agent to provision the machine. This allows for greater control and flexibility of the entire deployment process.
The ironic-python-agent may also be used with the original Ironic pxe drivers as of the Kilo OpenStack release.
