Thank you Jarome
I'm working with LXC , but should be applied for docker as well
I can connect the container through a virtio-user port in VPP, and a tap
interface in kernel
But we pay for a vhost kthread that is copying data from kernel to user
space and viceversa.
Another option is to connect with veth pair - but the performance is further
Another issue is how VPP interface with sandbox?
