It was reported that OM5P-AN needs not only a delay setting of 1 for RXD/RDV
but 2. These was found when testing with a NetGear GS752TP POE switch with a
cable length of 50ft and 250ft.

The tx/rx delay bits in the ETH_XMII_CONTROL register have to be unset when the
enable_rgmii_rx_delay/enable_rgmii_tx_delay will be set in the AT803x PHY.
Othwise the throughput in gigabit mode is heavily reduced.

The OM5P-AN boards are suffering from ethernet packet loss when booting with
some active POE setups or when switching to Fast Ethernet when previously
booted with Gigabit ethernet attached.
The cause of the problem is that the AR8035 PHYs requires special register
settings to work reliably on these boards. Enable the RGMII TX, RX delays and
disable SmartEE functionality of the AR8035 PHYs. Also enable the RXD and RDV
delay in the ETH_CFG register to fix the issue.
