The npages test against MAX_SKB_FRAGS can be relaxed if we succeed to 
allocate high order pages as the note in comment said.

We do not want this change.

This interface is used by datagram providers, we do not want to claim they can safely use skb allocations over 64KB.

Returning -EMSGSIZE should not depend on availability of high-order pages.

The comment was a hint, but we need first a valid user before considering expanding the interface.

I see. Many thanks for reply and explaination. :)
