David,

 

If anything goes wrong trying Damjan’s version, you can also look at example 
code for cloning packets.

Damjan, 

I'll test your version later today and report

Hemant,

Correct me if I'm wrong, but span mirroring mirrors all the traffic between 
physical interfaces. My use case
is mirroring some of the traffic coming to a node (according to some business 
logic) to a host interface.
