Embedded ethernet with high throughput

Archived from groups: comp.dcom.lans.ethernet (More info?)

Dear Friends
I want to have a ethernet connection to receive about 10Mbits/s UDP
packates from a LAN connection to my hardware board and then to process
it.
I have searched a lot of solutions for my project: from "single chip
LAN controllers in conjunction with a FPGA or a micro", to "Micro's
with built in LAN controller such as Maxim or Freescale's products",
and at lost I find Atmel's ARM based at91rm9200 a suitable choice. But
I doubt if a FPGA based CPU core such as the Nios II or MicroBlaze is
better choice.
Please help me to have the best choice.
thanks a lot
