High-performance TCP/IP networking for bhyve VMs using netmap passthrough

[Vincenzo Maffione]

Hello

Project summary
=================
ptnet is a new multi-queue paravirtualized device that builds on ptnetmap
to allow VMs to exchange TCP traffic at 20 Gbps, while still offering the
same ptnetmap performance (10-100 Mpps) to native netmap applications.
The purpose of this SOC project is to write a ptnet driver for FreeBSD and
a corresponding device model for the bhyve hypervisor.


Status update for week 6
===================
In this week I've added support for multi-queue netmap devices, done some
important bug-fixes in the datapth, and did several tests (ping, netperf)
to make sure the basic driver is working.
In the next week I will study how the virtio-net header works in FreeBSD
and start to extend the ptnet driver to support it.
