Capping will never let user know that memory is unnecessarily wasted as there is not much
Correlation between ring size and page pool size.  I would prefer not setting pool->p.pool_size in
Octeontx2  (pool->p.pool_size =  0 ) driver  and let page pool infra decide on that. Is this change acceptable ?
100G link burst traffic would be able to handle with 1024 page pool size, do we have any data with any other driver ?
