Hi,all
A friend Allan, Bruce W told me that there is no multiple Tx queue in
e1000e, because it does not make a difference in performance and only adds
to the complexity of the code.
Then, How can we get highest performance tuning with 64bytes small packets
on 5000P and 82571L ,with linux 2.6.30 OS?
Is there any kind friend who has the experience ? I need your help.
Thank you.
