Just saw that this patch depends on patch 5 of Maxime's series. And it needs a
small change because the generic function was renamed to
genphy_c45_pma_read_abilities(). So indeed it may be better if Maxime adds
this patch to his series.

One comment regarding the pause bits in Maxime's patch 5:
If no pause bit is set the core automatically sets both. So we have to do this
neither in the marvell10g driver nor in the generic read-abilities function.
