Gee, sorry... I meant _network_ applications, indeed. And, thank you for your
advice.
As for our performance troubles, there have been some improvements; we were
making some mistakes regarding both FCC and PHY programming. After fixing
those, we're able to achieve more than 50 Mbits/s in a _real_ FTP transfer,
which is more than enough for our router application. We are still
conducting more performance tests with netperf, and will publish the resuts
when available.
Thanks,
~Ricardo
