title: skb->priority and IP::tos and ping -Q
body: <p>I'm developing some network driver and I'm trying to assign packets to different queues basing on ip::tos value. For testing purposes I'm running:</p>
  
  <pre><code>ping -Q 1 10.0.0.2
  </code></pre>
  
  <p>to set ip::tos value to 1. The problem I've got is that on this system where I run ping command - outgoing skb has skb->priority==0, but I think it should be 1.</p>
  
  <p>I assumed that setting "-Q 1" will set skb->priority to 1, but it isn't. </p>
  
  <p>Anyone knows why?</p>
