How can I get these packets in the user space application?

[Ravi Kumar]

Lets say we wish to modify the packets in user space, then I think QUEUE 
is not the way, is my understanding right?

If so, what approach is followed to get packets to user space to modify 
them. Note that I understand performance issues in moving packets from 
kernel space to user space and back.
