This commit provides the initial delivery of support for the Auto-Attach standard to Open vSwitch. This standard describes a compact method of using IEEE 802.1AB Link Layer Discovery Protocol (LLDP) with a IEEE 802.1aq Shortest Path Bridging (SPB) network to automatically attach network devices not supporting IEEE 802.1ah to individual services in a SPB network. Specifically this commit adds base LLDP support to OVS along with the LLDP extension required to support Auto-Attach. The base LLDP code within this commit is adapted from the open source LLDPD project headed by Vincent Bernat. This base code is augmented with OVS specific logic which integrates LLDP into OVS and which extends LLDP to support Auto-Attach. The required build system changes are provided to include this new Auto-Attach feature. This is the first of a series of commits. Subsequent commits will be provided to complete the task of adding Auto-Attach to OVS.
