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 8 =================== In week 8 I advanced the implementation of virtio-net header support for the ptnet driver and tested the implementation using the QEMU hypervisor. I also added support for optional virtio-net-header selection, interface statistics and polling. During next week I will finalize the driver implementation and start to study bhyve code to adapt it to netmap.
