Merge branch 'net-mvpp2-rss-fixes'

Sven Auhagen says:

====================
net: mvpp2: rss fixes

This patch series fixes up some rss problems
in the mvpp2 driver.

The classifier is missing some fragmentation flags,
the parser has the QinQ headers switched and
the PPPoE Layer 4 detecion is not working
correctly.

This is leading to no or bad rss for the default
settings.
