Hello,
we're using a PCIe AR9280 card on a Octeon MIPS CPU. The system
that does the transmission has a high CPU utilization:
iperf in UDP mode with 50M bandwith has ~90 % CPU utilization with a
high softirq proportion.
Using an Intel card (5300) has a lower CPU utilization (~60 %), but it's
no

This is interesting. I have a problem with rate control (I guess) too. Can you
give me a clue
