From: Roopa Prabhu <redacted> New netlink api to associate tunnel info per vlan. This is used by bridge driver to send tunnel metadata to bridge ports in LWT tunnel dst metadata mode. 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. This patch also introduces a bridge port flag IFLA_BRPORT_LWT_VLAN to enable this feature on a tunnel bridge port. It is off by default.
