Re: veth interfaces

Hello,
thanks for the answer.

Using the KNI API, I create a new interface, and then I "push it into 
the container".
At this point, from the container, I send traffic and it is received in 
the KNI example program.

Instead, in my understanding, it is not possible to attach KNI to an 
already existing interface. Am I right?

Thank you,

     Ivano
