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