       skb_padto - pad an skbuff up to a minimal size


       struct sk_buff * skb_padto  (struct sk_buff * skb, unsigned int len);


       skb    buffer to pad

       len    minimal length


       Pads up a buffer to ensure the trailing bytes exist and are blanked. If
       the buffer already contains sufficient data it  is  untouched.  Returns
       the  buffer,  which  may be a replacement for the original, or NULL for
       out of memory - in which case the original buffer is still freed.
