I'm using a Omega2+ on a custom board with a SI-46020-F MagJack RJ-45 port connected to the omega's ethernet pins.

If I connect my laptop with a cross-over ethernet cable, I can SSH into the omega. But if I use a straight-through ethernet cable I cannot.

The RJ-45 port I'm using supports auto-MDIX, is there a way to enable this on the omega's side? Ethtool doesn't seem to be fully supported:
Settings for eth0:
Cannot get device settings: No such device
Current message level: 0x000000ff (255)
drv probe link timer ifdown ifup rx_err tx_err
Link detected: yes
