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 ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
