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 7
===================
In this week I've explored the FreeBSD code that deals with virtio-net
headers and related offloadings, so that I could start to incorporate them
into the ptnet driver. Together with various code improvements, I started
to implement virtio-net-header-aware datapath, both for the TX and RX side.
Next week will be used to complete the virtio-net header support and start
testing them through the QEMU hypervisor.
