This commit adds support for utilizing the VXLAN tunneling protocol in versions of Open vSwitch >= 1.10. This is configurable and will default to GRE if not configured. As part of this commit, it is possible to configure the UDP port VXLAN will utilize as well. VXLAN and GRE cannot be configured at the same time with this patch. 2 new configuration file options are added to the AGENT section of the config to support this: 'tunnel_type' and 'vxlan_udp_port'. In addition, the agent no longer makes use of enable_tunneling, as this can be determined if tunnel_type is set. Note: The VXLAN functionality utilized here is what is implemented in Open vSwitch itself, and is different than the VXLAN functionality in the upstream Linux kernel. The code validates both the userspace and kernel pieces of OVS to verify if VXLAN functionality can be supported on the running system Implements blueprint ovs-vxlan-lisp-tunnel Change-Id: I45d49d5d6463e574922c7f50d6499c6bdb6c862c
