Data throughput of embedded ethernet



Dear all
There are a lot of embedded ethernet cards out there now. I was considering the use of one of these to stream data from a fast serial ADC to PC for analysis - digital radio app.
What sort of data rate could be achieved for 2 16-24 bit I/Q words and what card would you use?
The max baseband bandwidth of the ADC is up to about 300KHz (ie 2 X 600KSamples/sec
What would be the limiting factor in this scenario?


Thanks
Richard
