Subject: EEE unsupported on enetc

In enetc_phylink_connect() we have the following:

/* disable EEE autoneg, until ENETC driver supports it */
memset(&edata, 0, sizeof(struct ethtool_keee));
phylink_ethtool_set_eee(priv->phylink, &edata);

Is it a hw constraint (if yes, on all IP versions?) that EEE isn't supported,
or is just some driver code for lpi timer handling missing?
Any plans to fix EEE in this driver?
