NF_QUEUE examples

[Ulysses Almeida <munky@maluco.com.br>]

  I alredy googled for this topic, but couldn't find any nice text
about.

  I want to understand more about NF_QUEUE return, and possibly use
it. So, where can i find simple examples of using it? Or a text
explaining about it.

  What I understand, is: with NF_QUEUE, I can queue some packet to be
manipulated on userspace. After this, can this packet be dequeued back
to kernel space, and continue with it's journey? How can I write a
userspace code, to handle with packetd queued bu NF_QUEUE? Or I didn't
understand nothing about it?

  Thanks for any help in advance!
