This series adds the multi-transports support to vsock, following this proposal: https://www.spinics.net/lists/netdev/msg575792.html With the multi-transports support, we can use VSOCK with nested VMs (using also different hypervisors) loading both guest->host and host->guest transports at the same time. Before this series, vmci-transport supported this behavior but only using VMware
