upstream has the following two properties (which need to be added
inside the Ethernet PHY devicetree node):
- eee-broken-100tx
- eee-broken-1000t
- (there are more, see Documentation/devicetree/bindings/net/ethernet-phy.yaml)

set them and EEE will not be advertised anymore.

there's some additional, AT803X PHY specific register write inside
at803x_disable_smarteee from
target/linux/generic/pending-4.14/734-net-phy-at803x-allow-to-configure-via-pdata.patch
This modifies the AT803X_PCS_SMART_EEE_CTRL3 register. I don't know
whether this is necessary when EEE is not advertised
