There's an increase in latency. For my application, I have no
problem keeping around a local patch that corrects this behavior
if folks don't feel it needs fixing. From everything I've ever
done in this space, having needless alloc/free calls in a
performance intensive path that requires low latency like a Lan
driver is not a good thing.
I am idle most of the time since I have eliminated all of the
copy activity by using SCI in the system. This is why it's
idle most of the time. Were I using the IP stack code in Linux
proper, the utilization would be through the roof.
