If a VxLAN device is attached to a VLAN aware bridge, it is possible to specify which VLAN IDs should map to which VNIs.

Using the bridge command, this is done using the tunnel_info and tunnelshow keywords, see https://man7.org/linux/man-pages/man8/bridge.8.html. See also https://developers.redhat.com/articles/2022/04/06/introduction-linux-bridging-commands-and-features in the section "VLAN tunnel mapping".

It would nice if the netlink library supported this.
