I knew VPP run in user space and that printk is not the best option,
however from the documentation it is not clear to me how to do that.
For example now I inserted the command clib_warning("I am here!") in the
node I create -- that from vppctl show trace I can see processes the
packets.
Where does it prints?
Still I cannot figure it out.
Thanks,
Alessio
