Sure it's possible 

In the hw you only need to duplicate the ethernet controller (TSE or whatever) and the related components, like DMAs or descriptor memory. 

The sw part can be a bit more tricky: it depends on how you use the Ethernet interfaces; I mean tcp stack, raw ethernet packet rx/tx or other.

Ok, thank you for your answer. 

I tried to create design with two igor mac (PHY DP83848) and it looks well. 

But can you suggest me PHY with gigabit speed ?  

I use DP83848, but it is 10/100Mbps. In some boards from Terasic they use Marvell 88E1111, but now i can not find in any electronic supplier - Digikey, Mouser ...  

 

Thank you again. 

 

Jan
