#304 200G single TCP flow

[Robert McMahon]

We get line rate (200Gbit NIC) one one single TCP flow, with BIG TCP.

In order to get this kind of performance :

• Zero copy on tx and rx

• 4K MTU (to enable rx zerocopy)

• BIG TCP

• CONFIG_MAX_SKB_FRAGS=45 kernel config

If you use 1500 MTU and standard tools, the bottlenecks are the copies
from/to user/kernel space.
