net: phy: honor eee_disabled_modes in phy_support_eee()#7373

phy_support_eee() copies supported_eee into advertising_eee unconditionally, overwriting any filtering that was applied during phy_probe() based on DT eee-broken-* properties or driver-populated eee_disabled_modes. As a result, MAC drivers that call phy_support_eee() after probe (e.g. bcmgenet, fec, lan743x, lan78xx, r8169) 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. Fixes: 49168d1 ("net: phy: Add phy_support_eee() indicating MAC support EEE") Signed-off-by: Nicolai Buchwitz <nb@tipi-net.de>
