    Add genphy_c45_config_aneg() function to phy-c45.c · 94acaeb5
    Marco Hartmann authored
    Commit 34786005 ("net: phy: prevent PHYs w/o Clause 22 regs from calling
    genphy_config_aneg") introduced a check that aborts phy_config_aneg()
    if the phy is a C45 phy.
    This causes phy_state_machine() to call phy_error() so that the phy
    ends up in PHY_HALTED state.
    
    Instead of returning -EOPNOTSUPP, call genphy_c45_config_aneg()
    (analogous to the C22 case) so that the state machine can run
    correctly.
    
    genphy_c45_config_aneg() closely resembles mv3310_config_aneg()
    in drivers/net/phy/marvell10g.c, excluding vendor specific
    configurations for 1000BaseT.
