====================
Ocelot PTP fixes

This is another attempt at "net: mscc: ocelot: be resilient to loss of
PTP packets during transmission".

The central change is in patch 4/5. It recovers a port from a very
reproducible condition where previously, it would become unable to take
any hardware TX timestamp.

Then we have patches 1/5 and 5/5 which are extra bug fixes.

Patches 2/5 and 3/5 are logical changes split out of the monolithic
patch previously submitted as v1, so that patch 4/5 is hopefully easier
to follow.
