Re: [dpdk-dev] [PATCH 0/4] l3fwd improvements

[Ruifeng Wang <Ruifeng.Wang@arm.com>]

Hello,

This patch series targeted to improve L3fwd example. Performance gain was observed on N1SDP platform.

It would be good if you can run this series on your platforms and see if there is any performance impact.

Thanks,
Ruifeng
