The set_bit() should go into the if statement above, since 6361 does not support usxgmii:

 /* 6361 only supports up to 2500BaseX */  if (!is_6361) {
        __set_bit(PHY_INTERFACE_MODE_5GBASER, supported);
        __set_bit(PHY_INTERFACE_MODE_10GBASER, supported);
+       __set_bit(PHY_INTERFACE_MODE_USXGMII, supported);
        config->mac_capabilities |= MAC_5000FD |
                MAC_10000FD;
 }
-/* FIXME: USXGMII is not supported yet */
-/* __set_bit(PHY_INTERFACE_MODE_USXGMII, supported); */
