bfa9a8a460 mbuf: rename data address helpers to IOVA
The following inline functions and macros have been renamed to be
consistent with the IOVA wording:

rte_mbuf_data_dma_addr         -> rte_mbuf_data_iova
rte_mbuf_data_dma_addr_default -> rte_mbuf_data_iova_default
rte_pktmbuf_mtophys            -> rte_pktmbuf_iova
rte_pktmbuf_mtophys_offset     -> rte_pktmbuf_iova_offset

The deprecated functions and macros are kept to avoid breaking the API.

d112a3ecb7 net/sfc: fix Tx reap behaviour on port stop on EF10 datapath
Tx reap mechanism on EF10 native datapath was altered by one
of the recent patches to introduce performance optimisations
using the common technique of freeing mbuf segments in bulks.

From this perspective, the way of associating SW descriptors
with individual mbuf segments rather than with whole packets
was adopted as a key requirement for the entire optimisation.

However, only the fast path reap function was amended to fit
the new scheme whilst the corresponding function on the port
stop path was left intact by mistake. This implies incorrect
usage of rte_pktmbuf_free() with regard to separate segments
rather than calling rte_pktmbuf_free_seg() and must be fixed.

3fd7797fcd net/sfc: check added but not completed descs on EF10 Tx reap
There is not point to check other Tx descriptors.
It is important if Tx datapath does not reset Tx descriptor
mbuf pointer to NULL on completion (EF10 simple Tx will do).
