Re: [PATCH net-next 06/12] rtnetlink: add new rtm tunnel api for tunnel id filtering

This patch adds new rtm tunnel msg and api for tunnel id
filtering in dst_metadata devices. First dst_metadata
device to use the api is vxlan driver with AF_BRIDGE
family.

This and later changes add ability in vxlan driver to do
tunnel id filtering (or vni filtering) on dst_metadata
devices. This is similar to vlan api in the vlan filtering bridge.
