4279b54e28 net/sfc: support Rx interrupts for efx datapath
When Rx interrupts are disabled, we simply disable rearm when
the interrupt fires the next time. So, the next packet will
trigger interrupt (if it is not happened yet after previous Rx
burst processing).

from NIC configuration instead of deprecated defines.

ffc905f3b8 ethdev: separate driver APIs
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.

47995190cf net/sfc: move event support init to attach stage
Prepare to fix device reconfigure.
Device arguments should be parsed once on attach.
Management event queue should be initialized once on attach.

6caeec4741 net/sfc: remove EvQ info array to simplify reconfigure
EvQ info array keeps information about EvQ centralized, however
EvQ pointers are available in TxQ and RxQ structures. Single
array for all EvQs complicates device reconfigure handling, so
simply git rid of it.

It removes notion of EvQ software index since there is no EvQ
array in software any more.

298951a402 net/sfc: bind EvQ DMA space to EvQ type and type-local index
The index of an event queue index is computed from the index of the
corresponding transmit or receive queue, and depends on the total
number of receive queues. As a consequence, the index of an event
queue bound to a transmit queue changes if the total number of
receive queues is changed.

dbdc82416b net/sfc: factor out libefx-based Tx datapath
Split control and datapath to make datapath substitutable and
possibly reusable with alternative control path.

libefx-based Tx datapath is bound to libefx control path, but
it should be possible to use other datapaths with alternative
control path(s).

7965557ede net/sfc: use different callbacks for event queues
Use different sets of libefx EvQ callbacks for management,
transmit and receive event queue. It makes event handling
more robust against unexpected events.

Also it is required for alternative datapath support.

The event queue is required for device level events (e.g. link status
change) and flush events.
Provide thread-safe function to poll the event queue since it may be
really done from different contexts.
