Removing support for legacy tunnel vport types, as they are not used with the kernel datapath for about 9 years now. The last in-tree user for them in dpif-netlink was Windows datapath that was also removed recently.
This increases the minimal kernel requirement for tunnel support to Linux 4.3 that added support for COLLECT_METADATA to various tunnel devices. However, this is not a huge loss, as the same kernel version is required for basic conntrack support, which is a very common action in most use cases. Many other features require higher kernel versions as well. It will still be possible to use OVS, through without tunnels, on older kernels. Users of OOT openvswitch module will still be able to use tunnels if the main kernel supports them, or if they bring the tunnel support to the kernel as separate OOT modules implementing RTM_NEWLINK for desired tunnel types. The last patch is the main removal, the first 3 are cleanup patches for the bits left after the kernel module removal form the OVS tree.
