SYNOPSIS

       struct sk_buff * pskb_copy  (struct sk_buff * skb, gfp_t gfp_mask);

DESCRIPTION

       Make  a  copy  of  both  an  &sk_buff  and part of its data, located in
       header. Fragmented data remain shared. This is  used  when  the  caller
       wishes  to modify only header of &sk_buff and needs private copy of the
       header to alter. Returns NULL on failure or the pointer to  the  buffer
       on success. The returned buffer has a reference count of 1.
