><P
> 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.
</P
><P
> &sk_buff MUST have reference count of 1.
</P
><P
> Returns <TT
CLASS="CONSTANT"
>NULL</TT
> (and &sk_buff does not change) if pull failed
or value of new tail of skb in the case of success.
</P
><P
> All the pointers pointing into skb header may change and must be
reloaded after call to this function.
