NAME
       skb_clone - duplicate an sk_buff


SYNOPSIS
       struct sk_buff * skb_clone  (struct sk_buff * skb, gfp_t gfp_mask);


ARGUMENTS
       skb    buffer to clone

       gfp_mask
              allocation priority


DESCRIPTION
       Duplicate  an  &sk_buff.  The  new  one  is not owned by a socket. Both
       copies share the same packet data but not structure. The new buffer has
       a  reference  count  of 1. If the allocation fails the function returns
       NULL otherwise the new buffer is returned.

       If  this  function  is  called  from  an  interrupt  gfp_mask  must  be
       GFP_ATOMIC.
