[PATCH net-next 7/7] net: phy: marvell10g: support other MACTYPEs

["Marek Behún" <kabel@kernel.org>]

Currently the only "changing" MACTYPE we support is when the PHY changes
between
  10gbase-r / 5gbase-r / 2500base-x / sgmii

Add support for
  xaui / 5gbase-r / 2500base-x / sgmii
  rxaui / 5gbase-r / 2500base-x / sgmii
