+description: |-
+ This plugin provides the beginnings of an integration with the
+ Linux network stack.
+ The plugin provides the capability to 'mirror' VPP interfaces in
+ the Linux kernel. This means that for any interface in VPP the user
+ can create a corresponding TAP or TUN device in the Linux kernel
+ and have VPP plumb them together.
+ The plumbing mechanics is different in each direction.
+ In the RX direction, all packets received on a given VPP interface
+ that are punted (i.e. are not dropped or forwarded) are transmitted
+ on its mirror interface (this includes for example ARP, ND etc,
+ so the recommendation is to disable ARP, ND, ping plugin).
+ In the TX direction, packets received by VPP an the mirror Tap/Tun
+ are cross-connected to the VPP interfaces. For IP packets, IP output
+ features are applied.
+ This is the beginnings of integration, because there needs to be
+ an external agent that will configure (and synchronize) the IP
+ configuration of the paired interfaces.
