MAC to MAC MII interface not working

I have a MAC to MAC MII interface between MPC8569 processor and BCM68610 controller , whose schematic design is followed from here. My linux kernel version is 2.6.32.

I want to ping one device from another. I have worked with MAC to PHY MII interface and it is working.

On processor side I have Ethernet port as eth2. I assigned IP to both devices in same network. (192.168.8.0/24)

According to guideline, I have to run this link in full duplex mode. So I checked output of ethtool

ethtool eth2

this is my output

    Supported ports: [ ]
    Supported link modes:   10baseT/Half 
                            100baseT/Full 
    Supports auto-negotiation: No
    Advertised link modes:  10baseT/Half 
                            100baseT/Full 
    Advertised auto-negotiation: No
    Speed: Unknown! (28271)
    Duplex: Unknown! (110)
    Port: MII
    PHYAD: 67
    Transceiver: external
    Auto-negotiation: off
    Current message level: 0x0000003f (63)
    Link detected: yes

It can not detect Speed and Duplex setting. In case of MAC to PHY MII interface, PHY configure this in kernel. What should be done in case of MAC to MAC MII interface ?

EDIT

I forcefully set the speed and duplex settings of link by editing driver/net/ucc_geth.c function in kernel source code. I made these changes in init_phy() function

if (priv->phy_interface==PHY_INTERFACE_MODE_MII){

    phydev->supported &= (ADVERTISED_10baseT_Half |
                 ADVERTISED_10baseT_Full |
                 ADVERTISED_100baseT_Half |
                 ADVERTISED_100baseT_Full);

    // here I am setting speed and duplex 
    phydev->speed = SPEED_100;
    phydev->duplex = DUPLEX_FULL;

    phydev->advertising = phydev->supported;
    priv->phydev = phydev;
    return 0;
}

After doing this, In output of ethtool eth2, speed and duplex fields were changed to

Speed: 100 Mb/s
Duplex: FULL

But still, I am not able to ping another device.
