net: dpaa2-mac: export standard statistics
Take advantage of all the newly added MAC counters available through the MC API and export them through the standard statistics structures - rmon, eth-ctrl, eth-mac and pause. A new version based feature is added into dpaa2-mac - DPAA2_MAC_FEATURE_STANDARD_STATS - and based on the two memory zones needed for gathering the MAC counters are setup for each statistics group. The dpmac_counter structure is extended with a new field - size_t offset - which is being used to instruct the dpaa2_mac_transfer_stats() function where exactly to store a counter value inside the standard statistics structure. The newly added support is used both in the dpaa2-eth driver as well as the dpaa2-switch one.
