NAME
       skb_scrub_packet - scrub an skb

SYNOPSIS
       void skb_scrub_packet(struct sk_buff * skb, bool xnet);

ARGUMENTS
       skb
           buffer to clean

       xnet
           packet is crossing netns

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