True - at this time. But what if this extension mechanism turns out to
be useful and we end up with more optional structures? I was hoping that

You're putting the extension in the skb->end area, right?

How big are the time stamps? If they're not that big, why don't
we put it into the shinfo structure itself? For the common case,
we have plenty of space due to kmalloc padding anyway.

Cheers,
