So there is no place at the end of skb for additional pointer.
And new question arises - until what Jesse suggested is implemented in
some way, do we need to store a pointer to shared info inside skb and
allocate it from cache in case it does no fit into aligned buffer (in
case of e1000 it happens all the time exept 1500 MTU)?
David, Herbert?
