Thanks for the follow up/clarification. From my initial netperf tests, I
am quite happy with the throughput of the card. The box only needs to push
30Mb/s, and it seems it can handle that in tests no problem. Not sure how
it will do in the real world, but I figure its worth a try since if this
works, there are a few other applications I can use this type of setup for!
