Does Ethernet PHy require external interrupt?

The S7G2 demo kit has an irq signal tied to the cpu.  I put a similar connection on my PCB.  Now when I set up the Ethernet PHY interface in the Synergy configurator I do not see a place to set up this interrupt.

Is this interrupt required???  

Where do I set it up if required?

Thanks for your help with this.
