I have an embedded linux board (main = board),=20 which has multiple Ethernet interfaces, and

a daughter card, which has one = Ethernet=20 interface. The diagram is shown as = following.

=20 +---------+ &n= bsp; &nb= sp; =20 +----------------------------+

| = daughter=20 |--------------------| ptp = &= nbsp; &n= bsp; |----------------

= | =20 card =20 | Ethernet &nbs= p; =20 | Main=20 board &n= bsp; =20 |---------------- Ethernet links with IP

+---------+ &= nbsp; &n= bsp; =20 | = &= nbsp; &n= bsp; =20 |---------------- =20 addresses

= &= nbsp; &n= bsp; &nb= sp; =20 +----------------------------+

I am looking for a method to manage = the=20 daughter card with single IP address. I tried to build

a point-to-point Ethernet link on = main board.=20 However, it does not = work.

Is there any solution to route = packets to ptp=20 port while the ptp port does not = have an IP=20 address?
