====================
Fixes for Ocelot driver statistics

This series contains bug fixes for the ocelot drivers (both switchdev
and DSA). Some concern the counters exposed to ethtool -S, and others to
the counters exposed to ifconfig. I'm aware that the changes are fairly
large, but I wanted to prioritize on a proper approach to addressing the
issues rather than a quick hack.

Some of the noticed problems:
- bad register offsets for some counters
- unhandled concurrency leading to corrupted counters
- unhandled 32-bit wraparound of ifconfig counters

The issues on the ocelot switchdev driver were noticed through code
inspection, I do not have the hardware to test.

This patch set necessarily converts ocelot->stats_lock from a mutex to a
spinlock. I know this affects Colin Foster's development with the SPI
controlled VSC7512. I have other changes prepared for net-next that
convert this back into a mutex (along with other changes in this area).
