NAME

       skb_peek_tail -

SYNOPSIS

       struct sk_buff * skb_peek_tail  (struct sk_buff_head * list_);

ARGUMENTS

       list_  list to peek at

DESCRIPTION

       Peek  an  &sk_buff.  Unlike most other operations you _MUST_ be careful
       with this one. A peek leaves the buffer on the list  and  someone  else
       may  run  off  with  it.  You must hold the appropriate locks or have a
       private queue to do this.

       Returns NULL for an empty list or a pointer to the  tail  element.  The
       reference  count  is  not  incremented  and  the reference is therefore
       volatile. Use with caution.
