New nested netlink attribute to associate tunnel info per vlan. This is used by bridge driver to send tunnel metadata to bridge ports in vlan tunnel mode. This patch also adds new per port flag IFLA_BRPORT_VLAN_TUNNEL to enable vlan tunnel mode. off by default. One example use for this is a vxlan bridging gateway or vtep which maps vlans to vn-segments (or vnis). User can configure per-vlan tunnel information which the bridge driver can use to bridge vlan into the corresponding vn-segment.
