So, as Eric already pointed out IIRC, there doesn't seem to be much value in enabling this IP in Linux - it should not be the default choice/highest priority, and it is not obvious to me whether/when you would prefer this implementation over the CPU based one. Do you have any idea how many queues it has, or how much data it can process in parallel? Are there other features that stand out?
