How many transmit queues do you have in operation:

/* Half-Duplex can only work with single queue */
if (priv->plat->tx_queues_to_use > 1)
priv->phylink_config.mac_capabilities &=
~(MAC_10HD | MAC_100HD | MAC_1000HD);

What does ethtool show before you force it? Does it actually list the
HALF modes?
