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.
