Cheng has recently done some performance testing. The short answer is, that the base stack is much less computationally intensive and better suited for datacenter / high performance environments, while the RACK stack is optimized for the common Internet Server (Wifi/relatively low bandwidth) client use case...<= /p>

Since fbsd is used in both these diverse environments, changing the default would probably lead to a different group of users having to tweak their settings off-default, while those who are already tweaking it, would no longer have to.

So, overall I don't see a compelling reason to change the default right now - but good reason to have both stacks around by default to be able to toggle between those if needed.

When receiving a packet over the virtio network channel, translate the virtio flag VIRTIO_NET_HDR_F_NEEDS_CSUM not to CSUM_DATA_VALID | CSUM_PSEUDO_HDR, but to CSUM_TCP, CSUM_TCP_IPV6, CSUM_UDP, or CSUM_UDP_IPV6. The second change fixes a series of issue related to checksum offloading for if_vtnet. While there, improve the stats counters to allow a detailed view on what is going on in relation to checksum offloading.
