Merge branch 'mvpp2-small-improvements' 

Antoine Tenart says:

====================
net: mvpp2: small improvements

Those 3 patches are small improvements to the Marvell PPv2 driver. The
series does not conflict with the one sent about phylink and
1000/2500baseX support, so the two series can live in parallel.
====================
