Using both EMACs but only one is working

I'm trying to use both EMACs on the XUPV5 as it is the middleman with two hosts connecting to it.

Host1 <=eth_link=> [EMAC0 ... fpga logic ... EMAC1] <=eth_link=> Host2

 

For some reason my EMAC0 will bring in data on rx_ll_data_0_i no matter the dst mac address and EMAC1 will never show anything on rx_ll_data_1_i on matter the dst mac address. I'm not sure if it has to do with the PHYAD or what. I have PHYAD_0 set to 00010 and PHYAD_1 set to 00111 (found these from other examples). Has anyone been able to use both EMACs with success? Any ideas on what to try?
