workload-aware acceleration

[huang195]

Not all packets benefit from sockmap redirection, namely those that are small, e.g., tens of bytes or smaller as it doesn't give packet coalescing a chance to make bigger packets out of smaller ones before transmitting, and packet headers will dominate resource usage. We could detect packet size distribution on a per-connection basis and accelerate only when appropriate. We could also accelerate only when packet size is greater than a certain threshold. Need to investigate if this makes sense.
