Hi,

 

   We are using two customized boards base on B4860. Now,we have a problem, we use "mac to mac connection" to realize the communication between the two boards.That is Fm1mac2=====backboard=====Fm1mac2.

   I change the device tree of fm1mac2 as follow:

   fm1mac2: ethernet@e2000 {
                phy-connection-type = "sgmii";
                fixed-link = <2 1 1000 0 0>;
    };

 

Now,two boards can communicate with each other, but the bandwidth can reach only 10Mbits/sec.

Do I need to change anything else?   thanks
