Subject: [PATCH net-next v2 0/3] net: phy: marvell-88x2222: a couple of improvements

First, there are some SFP modules that only uses RX_LOS for link
indication. Add check that link is operational before actual read of
line-side status.

Second, it is invalid to set 10G speed without autonegotiation,
according to phy_ethtool_ksettings_set(). Implement switching between
10GBase-R and 1000Base-X/SGMII if autonegotiation can't complete but
there is signal in line.

Changelog:
  v1 -> v2:
    * make checking that link is operational more friendly for
      trancievers without SFP cages.
    * split swapping 1G/10G modes into non-functional and functional
      commits for the sake of easier review.
