GigE support for 440GX is in official 2.6. Patch for 2.4 is available at http://kernel.ebshome.net. If you don't feel comfortable dealing with kernel patches, I'd recommend 2.6 Effective Ethernet throughput highly depends on packet size. For some small packet sizes 600Mb/s is theoretically impossible over GigE. I achieved 900+ Mb/s TCP throughput with my driver (packets around 4K long) and using sendfile(2) based test application. -- Eugene
