Using onchip Ethernet with Cerberus

Does anyone know how to use the onchip ethernet of the STM32F407 instead of the external ENC28 board?
Any plan to support this feature?

@ Cybernox - Our [em]Mountaineer Ethernet Mainboard [/em] (https://www.ghielectronics.com/catalog/product/385) does exactly this. The Ethernet driver written by our friends at [em]CSA Engineering[/em], as part of the [em]NETMF for STM32 [/em]port of NETMF, uses the Ethernet hardware built into the STM32 microcontroller.
