NAME
       __pskb_pull_tail - advance tail of skb header

SYNOPSIS
       unsigned char * __pskb_pull_tail(struct sk_buff * skb, int delta);

ARGUMENTS
       skb
	   buffer to reallocate

       delta
	   number of bytes to advance tail

DESCRIPTION
       The function makes a sense only on a fragmented sk_buff, it expands
       header moving its tail forward and copying necessary data from
       fragmented part.

       sk_buff MUST have reference count of 1.

       Returns NULL (and sk_buff does not change) if pull failed or value of
       new tail of skb in the case of success.

       All the pointers pointing into skb header may change and must be
       reloaded after call to this function.
