determine when all pending Tx frames have been processed by hardware

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.
