from NIC configuration instead of deprecated defines.

If Rx datapath supports multi-process, secondary process should be
able to use Rx descriptor status and related API.

Equal stride super-buffer Rx mode allows to mark packets in HW
using filters. Process the data on datapath and advertise
corresponding features to allow flow API support to implement it.

The callback is a dummy yet since no Rx datapath provides its own
callback, so all pools are supported.

HW Rx descriptor represents many contiguous packet buffers which
follow each other. Number of buffers, stride and maximum DMA
length are setup-time configurable per Rx queue based on provided
mempool. The mempool must support contiguous block allocation and
get info API to retrieve number of objects in the block.

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.

Create a rte_ethdev_driver.h file and move PMD specific APIs here.
Drivers updated to include this new header file.
There is no update in header content and since ethdev.h included by
ethdev_driver.h, nothing changed from driver point of view, only
logically grouping of APIs. From applications point of view they can't
access to driver specific APIs anymore and they shouldn't.
More PMD specific data structures still remain in ethdev.h because of
inline functions in header use them. Those will be handled separately.

EFX_RXQ_LIMIT is libefx-specifics and it should not be used
for other Rx datapaths implementations (e.g. EF10 native).
EF10 native Rx datapath has its own understanding of the maximum
RxQ fill level imposed by EvQ clear strategy and space reserved
for Rx error and flush events.
