Did  you  saw  the  "Marvel 88E6060 PHY driver attached" string in the
kernel messages? If so then at least the driver detects switch chip.

This driver uses VLAN tags to determine which port the frame should be
sent from. Try to create couple of VLAN sub-interfaces on eth0 with ID
1 and 2 and work with them.

And BTW do you use OpenWRT or LEDE and which version?
