openvswitch: Support VXLAN Group Policy extension Introduces support for the group policy extension to the VXLAN virtual port. The extension is disabled by default and only enabled if the user has provided the respective configuration. ovs-vsctl add-port br0 vxlan0 -- \ set Interface vxlan0 type=vxlan options:exts=gbp The configuration interface to enable the extension is based on a new attribute OVS_VXLAN_EXT_GBP nested inside OVS_TUNNEL_ATTR_EXTENSION which can carry additional extensions as needed in the future. The group policy metadata is stored as binary blob (struct ovs_vxlan_opts) internally just like Geneve options but transported as nested Netlink attributes to user space. Renames the existing TUNNEL_OPTIONS_PRESENT to TUNNEL_GENEVE_OPT with the binary value kept intact, a new flag TUNNEL_VXLAN_OPT is introduced. The attributes OVS_TUNNEL_KEY_ATTR_VXLAN_OPTS and existing OVS_TUNNEL_KEY_ATTR_GENEVE_OPTS are implemented mutually exclusive. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.
