title: NetLink Message Memory Issue
body: <p>I am trying to send messages from user space to kernel. I am able to send it succesfully via netlink sockets. But I would like to know whether I should free the messages in kernel function which I have written or netlink socket API's are deallocating memory? </p>
  
  <p>Also in /proc/net/netlink, I can see the Drop counts keep on increasing. What this count signifies? </p>
