"Using Triple-Speed Ethernet on DE2-115 Boards" doesn't work

The tutorial files are located here: 

ftp://ftp.altera.com/up/pub/altera_m...2.0/tutorials/ (ftp://ftp.altera.com/up/pub/altera_material/12.0/tutorials/

 

I can't attach the Qsys system, but I can attach a screenshot of it.... 

 

The problem is the ISR never gets called to receive the packet... It does appear to send though 

here's what shows in the debug window: 

Opened scatter-gather dma transmit device 

Opened scatter-gather dma receive device 

send>  

TEST1234TEST 

TEST1234TEST 

send>  

 

There should be a receive in there, but I can't figure out why... the Qsys and QuartusII part of the tutorial built without errors... I'm guessing that something isn't hooked up correctly in the Qsys picture...  

 

Thanks.
