DESCRIPTION

19       skb_scrub_packet can be used after encapsulating or decapsulting a
20       packet into/from a tunnel. Some information have to be cleared during
21       these operations. skb_scrub_packet can also be used to clean a skb
22       before injecting it in another namespace (xnet == true). We have to
23       clear all information in the skb that could impact namespace isolation.
