Hi Meenal,

As far as I can tell there are a couple of ways we can get there.  The
most straight-forward is to use the tap/tun interface to create either
a pseudo IP or ethernet port from user space.  The kernel and the rest
of the networking stack is on one end, GNU Radio would be on the

Click isn't a requirement, it's more of an example of how things could
be made to work.  [And a source of examples of how to get packets in
and out of the kernel from users space.]
