Backplane communication with I210 IS

Hello together,

I want to realize a backplane communication with two I210 IS Ethernet controller. My intention is to use SGMII or SERDES interface.

Is there an application note available how to realize such an application?

I have to realize a communication of two processors via. Ethernet. The whole system is designed on only one circuit card. From upper software point of view the system should react like two separated processor systems which are connected via LAN cable. I tried to show it in a small sketch below.

Thanks in advance,

Maximilian
