The Movidis X16 bootloader doesn't enable the mdio bus. The first patch fixes this by enabling the mdio bus when the driver is initialized. Also the addresses of the PHYs was unknown for this device. The second patch adds the corresponding PHY addresses. With both patches applied I can successfully use all eight Ethernet ports. Please consider for 2.6.34. Since Octeon is an embedded MIPS SOC it is unlikely to break the kernel for any workstations. Any or all of these could be considered for merging via Ralf's linux-mips.org tree.
