[PATCH v5] net/af_xdp: parse umem map info from mempool range api

[Morten Brørup]

> From: Frank Du [mailto:frank.du at intel.com]

> The current calculation assumes that the mbufs are contiguous. However,
> this assumption is incorrect when the mbuf memory spans across huge page.
> 
> Correct to directly read with mempool get range API.

> v2:
> * Add virtual contiguous detect for for multiple memhdrs
> v3:
> * Use RTE_ALIGN_FLOOR to get the aligned addr
> * Add check on the first memhdr of memory chunks
> v4:
> * Replace the iterating with simple nb_mem_chunks check
> v5:
> * Use rte_mempool_get_mem_range to query the mempool range
