DUMPING ETHERNET DATA TO PL WITHOUT OVERHEAD

Hi everyone,
 
 
I would like to redirect Ethernet payload comming/going from/to Eth0 port on zedboard without requiring intervention from PS (although it can provide initial configurations). In other words, i would like to use the EMAC on the PS and pipe data to an AXI interface, as Tri-Mode-Ethernet MAC does. The reason to do this is that the application is an LTE transceiver and i need data to flow between Ethernet and RF ASAP and software might introduce excessive overhead. 
 
Can someone tell me if this is feasible?
