14480454c7 driver: net: ldpaa: Fix Rx buffer alignment
MC 0.7.1.2 enforces limitation i.e.: "Packets may be corrupted
in several combinations of buffer size and frame offsets.
Workaround: Use buffers that are of size that is a multiple of 256, and
frame offset that is a multiple of 256"

Updating the DPNI Eth driver to comply with the restriction.

c919ab9ee5 driver: net: ldpaa: Use DPMAC as net device
As per current implementation of DPAA2 ethernet driver DPNI is used as
net device. DPNI is tangible objects can be multiple connected to same physical lane.

Use DPMAC as net device where it represents physical lane.
Below modification done in driver
 - Use global DPNI object
 - Connect DPMAC to DPNI
 - Create and destroy DPMAC

0c7c87a4ac driver/ldpaa_eth: Avoid TX conf frames
Polling of TX conf frames is not a mandatory option.
Packets can be transferred via WRIOP without TX conf frame.

Configure ldpaa_eth driver to use TX path without confirmation frame

9cc2c4713a driver/ldpaa: Add support of WRIOP static data structure
Wire rate IO Processor (WRIOP) provide support of receive and transmit
ethernet frames from the ethernet MAC.  Here Each WRIOP block supports
upto 64 DPMACs.

Create a house keeping data structure to support upto 16 DPMACs and
store external phy related information.

c517771ae7 driver/ldpaa_eth: Add LDPAA Ethernet driver
LDPAA Ethernet driver is a freescale's new ethernet driver based on
Layerscape architecture.

Every ethernet driver controls on DPNI object. Where all DPNIs share
one common DPBP and DPIO object to support  Rx and Tx flows.
