714bff55a4 net/sfc: support runtime VI window size
Medford2 uses a configurable VI window size, and requires
updates to register accesses to use a runtime VI window size
rather than the *_STEP register constants used for earlier
controllers.

91d1627654 net/sfc: prepare to merge init logs with main log type
Conversion to dynamic logging done in the previous patches
makes it possible to simplify internal controls for init
logging. This patch allows to prepare for such a change.
It makes init-unrelated messages use NOTICE level so that
the following patch will be able to convert init logging
to use INFO level and remain silent by default.

c78d280e88 net/sfc: convert to new Tx offload API
Ethdev Tx offloads API has changed since:
commit cba7f53b717d ("ethdev: introduce Tx queue offloads API")
This commit support the new Tx offloads API.

The code which fills in txq_flags in default_txconf is preserved
because rte_eth_dev_info_get() lacks conversion between offloads
and txq_flags fields which means that a legacy application which
relies on default_txconf will fail to configure Tx queues in the
case when some bits in txq_flags are mandatory.

048da2530d net/sfc: avoid Tx queue setup failure if thresholds are set

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.
