Merge branch 'dpaa2-eth-Add-new-statistics-counters'
Ioana Radulescu says:
====================
dpaa2-eth: Add new statistics counters
Recent firmware versions offer access to more DPNI statistics
counters. Add the relevant ones to ethtool interface stats.
Also we can now make use of a new counter for in flight egress frames
to avoid sleeping an arbitrary amount of time in the ndo_stop routine.
v2: in patch 2/3, treat separately the error case for unsupported
statistics pages
