Hi all,
We want to get a data rate of 600Mbits/s over gigabit ethernet of ppc440gx.
How about the status of support to ppc440gx GigE in Linux kernel?
Which kernel version should we select? 2.6 or 2.4?
Thanks a lot!

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.
