net: phy: honor eee_disabled_modes in phy_support_eee()
phy_support_eee() copies supported_eee into advertising_eee
unconditionally, overwriting any filtering applied during phy_probe()
based on DT eee-broken-* properties or driver-populated
eee_disabled_modes. MAC drivers that call phy_support_eee() after
probe (e.g. bcmgenet, fec, lan743x, lan78xx, r8169) then cause the PHY
to advertise EEE for modes the user marked as broken.
The symptom is that ethtool --show-eee on the local interface reports
"not supported" (supported & ~eee_disabled_modes is empty) while the
link partner sees EEE negotiated and active.
phy_probe() already filters advertising_eee via eee_disabled_modes
after calling of_set_phy_eee_broken(). Apply the same mask in
phy_support_eee() so the filtering survives the copy.
