[dpdk-dev] [PATCH 0/2] L3FWD sample optimisation

[Konstantin Ananyev]

With latest HW and optimised RX/TX path there is a huge gap between
tespmd iofwd and l3fwd performance results.
So there is an attempt to optimise l3fwd LPM code path and reduce the gap:
 - Instead of processing each input packet up to completion -      
 divide packet processing into several stages and perform      
 stage by stage for the whole burst.
 - Unroll things by the factor of 4 whenever possible.
 - Use SSE instincts for some operations (bswap, replace MAC addresses, etc).
 - Avoid TX packet buffering whenever possible.
 - Move some checks from RX/TX into setup phase.
