We have researching this topic for a little while, particularly from the FPGA standpoint. Although not specific to MIPS, I offer a
few links which discuss the considerations for successfully sustaining gigabit ethernet transport.
The "Gigabit System Reference Design", pg. 49 offers some benchmarks obtained using MontaVista Linux on a PowerPC 405. Key
takeaways are that the data payload must not be handled by the stack (DMA direct from framebuffer/fifo/sdram) and must use jumbo
(5000,9000) ethernet frames.
