Hi all,
I've got a au1550 board based largely on the pb1550. The ethernet throughput is ~66Mbps using the 2.6 kernel. This also consumes a
lot of cpu cycles to send.

We have older designs using au1000 and mvista 2.4 kernel that achieve full line rate throughput without using a lot of the cpu.

Can someone with a pb/db1550 and linux 2.6 do a quick test to verify
that is is not a 2.6 kernel problem, and is a problem with our HW/SW.

If anyone can do the same with a 2.4 kernel too that would be great.

Thanks,
JP
